At the core of every metal-handling industry lies a daily challenge: lifting, moving, and positioning heavy loads efficiently, safely, and without wasting energy. Have you ever wondered how enormous steel plates are handled in shipyards? Or how scrap metal is sorted and transported in recycling facilities? There is one answer: lifting electromagnets.

We’re not talking about science fiction, but applied engineering. A simple electric impulse, and a seemingly immovable metal block lifts off the ground as if it were weightless. One click is all it takes to release it precisely where needed. No straps, no hooks, no chains—just the power of controlled magnetism: precise, reliable, and powerful.

And if you think this is a luxury for a select few, think again. Lifting electromagnets are now an accessible solution for anyone working with ferrous materials from small workshops to large steel mills. We’ll explore how they work, the advantages they offer, and the key applications that make them indispensable. Most importantly, we’ll help you choose the right model for your needs, because every load has its ideal electromagnet.

Get ready to discover a technology that not only lifts metal—but also raises your company’s efficiency to the next level.

A lifting electromagnet is an essential tool for anyone working with metal who needs to move it quickly, safely, and efficiently. It is commonly used in construction sites, steel plants, scrap yards, and many other industrial sectors to lift, collect, and handle ferrous materials such as metal sheets, beams, pipes, and scrap metal.

Unlike a regular magnet, an electromagnet has a special feature: it can be switched on and off at will. This characteristic makes it exceptionally suited for industrial applications that demand high precision and full control over load handling. There are three main types of lifting electromagnets:

• Hydraulic magnets, ideal for heavy-duty applications and environments that require high operational durability, such as demolition sites.
• 220V externally powered magnets, connected directly to the electrical mains, perfect for continuous lifting operations.
• Battery-powered electromagnets, offering freedom of movement without the need for a direct power connection.

Each of these systems operates based on different principles, making them suitable for specific contexts. But one thing is certain: if you need to lift metal intelligently, an electromagnet is the perfect solution.

A lifting electromagnet is like a gravity switch: turn it on, and the metal rises; turn it off, and it’s released with pinpoint accuracy. Its secret? Electricity transformed into pure magnetic force.

It all begins when an electric current flows through a copper or aluminium wire wound around a metal core. In that moment, an invisible magnetic field comes to life and becomes an incredibly powerful anchor for any ferromagnetic material nearby. The result? The load clings to the electromagnet as if gripped by an invisible force.

And here’s the real advantage: no hooks, ropes, or complex mechanical systems. Just one click to activate and another to release it—with a level of precision unmatched by any other lifting technology. It’s a dance of power, electricity, and total control over metal.

Imagine harnessing the power of pressurised oil to activate a magnet capable of lifting scrap metal, steel plates, and beams as if they were feathers. That’s exactly how hydraulic electromagnets work: they connect to the hydraulic system of heavy machinery such as excavators and loaders and convert hydraulic pressure into an incredibly powerful magnetic field.

They require no electrical power supply, making them ideal for tough working conditions or remote locations where grid electricity is unavailable. Simply activate the oil flow to magnetise the load and stop it to release. For this reason, they are the secret weapon of demolition crews, scrap handlers, and recycling centre operators who manage vast quantities of metal daily with maximum efficiency.

When it comes to industrial magnetic lifting, electric electromagnets reign supreme. This technology uses a ferromagnetic core wrapped in coils of copper or aluminium wire: when electric current flows through the coils, an exceptionally strong magnetic field is generated.

Electric magnets are reliable, precise, and ideal for continuous industrial use, where magnetic force control is crucial and external power is required. They are commonly used in steel mills, logistics warehouses, and manufacturing facilities where metal must be moved quickly and without error. With these magnets, lifting and moving metal becomes remarkably easy—with just the flick of a switch.

When the power of magnetism meets the freedom of mobility, battery-powered electromagnets come into play. These devices operate via an integrated battery, making them independent from both the electrical grid and hydraulic systems. In other words, they can be taken anywhere and used without restrictions.

Some models are designed with built-in batteries, while others can be connected to an external power source. The real highlight? Remote control. With a wireless remote, the magnetic field can be activated or deactivated with pinpoint accuracy—enhancing operator safety and increasing handling speed.

Used in construction, demolition sites, and logistics operations, these magnets are built to handle any challenge—from lifting heavy beams to collecting small ferrous fragments. If you’re looking for maximum flexibility and convenience, a battery-powered electromagnet is the winning choice.

You can’t see it, you can’t touch it, but it has the power to lift tonnes of metal with surgical precision. The magnetic field is the beating heart of every lifting electromagnet—the invisible engine that converts electrical energy into pure attractive force.

But what determines its strength? Three key elements make all the difference:

• Electric current: the more electricity flows through the copper or aluminium winding, the stronger the magnetic field becomes—ready to grip and hold the load.
• Number of coil turns: a wire wound hundreds or thousands of times amplifies the magnetic effect, turning a simple coil into a formidable lifting magnet.
• Ferromagnetic core: if the core of the electromagnet is made of a material with high magnetic permeability, the field becomes even stronger and more stable.

Here lies the true advantage: this magnetic field can be switched on and off at will, allowing for pinpoint control over the grip on metal. One electrical impulse, and the load is lifted. Another, and it’s released exactly where it needs to be. Maximum power, total control, zero waste. This is the magic of electromagnetism applied to lifting.

If you work with metal, you know that lifting, moving, and positioning it can be a time-consuming and risky process. But what if there were a faster, safer, and more efficient way to get the job done? Lifting electromagnets are the game-changing answer to modern material handling. Here’s why more and more companies are choosing them:

• Profitability: reinforced concrete blocks contain up to 10% rebar. With continuous use, a lifting magnet can pay for itself in under six months.
• Operational efficiency: the ability to quickly switch the magnetic field on and off allows for fast material handling, cutting down loading and unloading times.
• Flexibility: whether you’re lifting thin sheets, massive beams, or irregular metal scrap, the electromagnet adapts with ease. A single tool to manage materials of all shapes and sizes—no need to change equipment.
• Safety: less human contact means fewer hazards. Operators no longer need to approach the load to attach or detach metal, dramatically reducing the risk of workplace accidents. Additionally, the lack of mechanical moving parts minimises breakdowns and the need for unexpected maintenance.
• Cost savings: more speed + fewer errors = lower operating costs. Optimising handling time cuts down energy consumption and labour costs. It also reduces damage to conveyor belts in shredding plants and prevents system blockages. A lifting electromagnet isn’t just a purchase—it’s a smart investment that pays off over time.

Lifting electromagnets are the solution for moving ferrous materials quickly and safely in construction sites, steel mills, demolition sites and recycling plants. However, not all metals respond to the pull of magnetism. Which materials can be lifted and which remain unaffected by magnetic force?

To be lifted by an electromagnet, a material must be ferromagnetic, meaning it must contain iron, nickel or cobalt. Among the most common are:

• Carbon steel → The undisputed king of construction and manufacturing industries, widely used for structures, machinery, and industrial components.
• Cast iron → Heavy, strong and widely used in the production of mechanical parts and industrial infrastructure.
• Ferritic stainless steel → Not all stainless steels are magnetic, but some ferritic alloys respond well to electromagnets.
• Magnetite and other iron minerals → It’s not only metals, but some iron-rich rocks can also be lifted by magnetism.

Not all metals are attracted to a magnetic field. Some, such as aluminium, copper and most austenitic stainless steels, remain unaffected by an electromagnet’s pull. This means that if your load is composed of these materials, you’ll need to consider alternative lifting systems such as grapples or suction cups.

If you are considering purchasing a lifting electromagnet, it is essential to take several factors into account to ensure the device matches your operational requirements.

Not all lifting electromagnets are the same. Depending on the type of material to be lifted and the working environment, different solutions can optimise your handling operations.

• Hydraulic magnets

Ideal for collecting scrap metal and ferrous materials in demolition sites and scrap yards. They connect to the hydraulic circuits of excavators and loaders, ensuring a secure grip even under the toughest conditions.

• 220V and 24V circular electromagnets

When it comes to collecting and moving scrap metal, circular electromagnets are the most common solution. Available in various sizes and power ratings, they are powered by generators mounted on the machines to which they are attached.

• Battery-powered electromagnets with remote control

For those seeking total independence, these magnets are the perfect choice. They do not require an external power supply and can be operated remotely via a radio controller, making metal lifting even faster and safer.

• Magnets powered by diesel and petrol

For operations in remote areas or on machinery that cannot support electric or hydraulic supplies, there are electromagnets equipped with diesel or petrol engines. These devices have an autonomous generator that provides the necessary power to create the magnetic field, making them perfect for outdoor work or extreme conditions.

• Electromagnets for polyp grabs

Polyp grapple electromagnets are designed to be mounted on mechanical grapples, such as those used in demolition or material recovery centres. Their magnetic force combines with the mechanical action of the grab, enabling the collection and retention of even small metallic fragments, ensuring cleaner sites and more efficient ferrous material management.

If you are looking for a lifting electromagnet for your business, carefully assess the load capacity, power supply type, size and environmental conditions of use. Investing in a quality model ensures safety, reliability, and better long-term operational performance.

What safety precautions should be taken when using lifting electromagnets?

It is essential to avoid overloading, keep the power supply system stable and regularly check the state of the electromagnet to prevent sudden failures. In addition, operators must be properly trained.

Can I use an electromagnet to lift painted or rusted objects?

Yes, but the lifting effectiveness may be reduced. Rust or paint creates a layer between the material and the electromagnet, decreasing the force of attraction.

Can lifting electromagnets be used outdoors?

Yes, but it is advisable to choose models with adequate IP protection to withstand rain, dust and temperature variations.

How can I increase the lifetime of my lifting electromagnet?

By carrying out regular maintenance, avoiding overheating and always using it within the specified capacity limits. 

Can lifting magnets be used to lift non-ferrous materials?

No, lifting magnets are only designed to attract and lift ferrous materials, such as iron, steel and cast iron. Non-ferrous metals, such as aluminium, copper or brass, do not respond to the magnetic field and therefore cannot be lifted with this technology.

Can electromagnets be used for underwater lifting?

Yes, there are electromagnets specifically designed for underwater operations. These devices are built with waterproof materials and corrosion protection systems, allowing safe operation even in submerged environments such as ports, hydroelectric plants, or maritime recovery operations.

How attractive is an electromagnet?

There is no single answer—it depends on the type of material being handled. Are you lifting solid blocks of iron or cast iron, rebar, machining chips, crushed scrap, or something else?

Each material has specific characteristics that influence the choice of the ideal electromagnet. Contact us, tell us about your needs, and we will assess the situation together. Our technical team is always available to provide personalised advice and all the information you need to find the most suitable solution for your operational requirements.

How to choose the correct magnet size?

Once the most suitable type has been identified, the choice of the correct electromagnet size depends on the operating weight of the carrier machine: for excavators, the operating weight should be at least 10 times greater than the magnet’s weight to ensure stability and safety during use. For other types of machines, it is important to refer to the technical lifting data to choose the most appropriate magnet size.

For hydraulic electromagnets, it is also crucial to assess the characteristics of the machine’s hydraulic system. For electric magnets, careful analysis of the available power supply parameters is required.
