  • How does a electromagnet / solenoid work?

    We have often been asked by business partners how an electromagnet works. For this reason we decided to make a short contribution.

    How it works:

    • Electrical energy is converted into magnetic energy and then again into mechanical energy.
    • Current flows through the copper coil (2), creating a magnetic field. Through this, a force is exerted by the armature (3), which moves in the direction of an iron core (1).
    • Since the elements, iron core (1), armature (3) and housing (5) are made of ferromagnetic material, when a magnetic flux passes through them, they try to establish an ideal state. As a result, the armature (3) tries to close the air gap (4) and moves towards the iron core (1).
    • Electromagnets are mainly used as drive elements to generate linear and rotatory movements such as moving, holding, switching, controlling.
    • Unlike permanent magnets, where the magnetic force is constant, the magnetic field of electromagnets can be regulated depending on the current flow. Thus, the mechanical force can be controlled or turned off depending on the current flow.


    • Locking systems, magnetic clutches, diaphragm pumps.
    • Dosing systems in medical technology and beverage vending machines (hose clamp valves)
    • Automation and assembly technology
    • In the field of hydrogen
    • Electrical handheld devices
    • Conveyor technology (elevators, escalators)
    • Mobile hydraulics (cranes, rollers, excavators)
