Electromagnets

An electromagnet works by passing current through the coil, which creates a magnetic field that generates a holding force. This force is strongest when the magnet is used against a flat iron material of sufficient thickness – preferably the same size or larger than the holding surface of the electromagnet. The minimum required material thickness is stated for each model in the respective data sheet.

These magnets offer an impressive holding force when activated with current, from 120 N up to a full 5500 N. In de-energized operation – when the coil does not generate any magnetic field – there is still a holding force of between 120 N and 2000 N. This makes these electromagnets particularly well suited for applications in security, access control and various types of automation.

To optimize the function of the magnet, retaining plates and accessories are available for the models BEM3, BEM4, BEM5 and BEM6. Regardless of the application, the right choice of coil, material and magnet ensures a reliable and powerful solution.

Electromagnets – powerful solutions for industry and automation

Electromagnets play a key role in many modern technological systems. They are used to create a strong magnetic field when an electric current is applied, making it possible to hold, lock or lift metal objects with high precision. Their flexibility and reliability make them an obvious solution in everything from industrial automation to safety devices.

High holding force for demanding applications

Our electromagnets are designed to provide maximum holding force when used against a flat surface of sufficient thickness. For best performance, the part being handled should have a dimension that is equal to, or greater than, the electromagnet's holding surface. Recommended minimum material thickness is stated in the respective product data sheet.

Two holding power options:

  • Powered holding force – from 120 N to 5500 N. Ideal when the electromagnet only needs to hold under power supply.
  • Currentless holding force (permanent magnet) – from 120 N to 2000 N. Perfect when you need protection even in the event of a power outage.

Applications of electromagnets

Electromagnets are particularly popular in the following areas:

  • Access control – such as electric strikes, door magnets and access control systems.
  • Safety – where reliable locking is required even during downtime.
  • Automation projects – where fast and controlled magnetic functions are needed in machines or robotics.

Accessories for optimized function

For the BEM3, BEM4, BEM5 and BEM6 models, we offer matching holding plates and accessories. These help create optimal contact between the electromagnet and the surface, which improves holding force and increases the reliability of the system.

Advantages of our products

  • Wide range of holding forces and models
  • Options for both powered and unpowered applications
  • Suitable for everything from simple installations to complex automation
  • High quality and custom accessories for easy integration

Frequently asked questions about electromagnets

What is an electromagnet?

An electromagnet is a magnet whose magnetic field is created by passing electric current through a coil wound around a ferromagnetic core. When the current is turned off, the magnetic field disappears – making electromagnets temporary and controllable.

When electricity flows through the coil, a magnetic field is created that magnetizes the core, creating force – for example, to hold or lift metal objects. The magnetic strength increases with more coil turns, higher current, or a denser soft iron core. When the current is interrupted, the magnetic field disappears.

There are several types, including industrial holding magnets for heavy lifting, plasma magnets for precision applications and door holders for fireproof environments. Sweden's BEM series (e.g. BEM9, BEM10, BEM13) offers holding forces from ~12kg to ~180kg in various designs.

Electromagnets are used in a range of areas – from lifting scrap in industries and controlling loudspeakers, to holding fire doors open and as magnetic locks. They are also used in medical equipment, automation and heavy industrial applications.

An electromagnet requires electricity to generate magnetism, while a permanent magnet is always magnetic. Electromagnets can be easily turned off, making them more flexible in controllable systems.

To choose the right electromagnet, you should adapt the solution to the application's holding force (kgf), voltage range (e.g. 12–220V DC), protection class (IP class) and environmental conditions. With technical documentation and support from Elektrokomponenter, you can easily dimension the right model for your application.
