An electromagnet often comprises a copper wire wound round a core made of a soft magnetic material such as iron. The strength of the electromagnet depends on the numbers of turns of the winding and the current through the winding, up to the level at which the core is saturated. When the current through the winding disappears, the electromagnet also loses its magnetic field. It is therefore possible to switch a magnetic field for electromagnets on or off in this way.

Electromagnets have a wide range of applications, ranging from the largest applications such as lifting scrap to small applications in medical technology.


Holding magnet

Used to a large extent as holding magnets for doors, often in conjunction with fire protection, and deactivated when the current in the coil is switched off. They are also used in the field of hydraulics and for safety doors in the field of automation. Can be supplied in both a round and rectangular design.


Holding magnet with permanent magnet

A holding magnet containing an integrated permanent magnet. The holding force comes from the permanent magnet and the current in the coil deactivates the magnet and neutralises the force. Suitable for applications where there is a risk of power failures or can be used to save energy.
