How does an Electromagnet work?

How does an Electromagnet 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 anchor (3), which moves in the direction of an iron core (1).
  • Since the elements, iron core (1), anchor (3) and case (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 slot (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.
    In contrast to 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.
