How do inductors store energy?
$begingroup$ As capacitors store energy in the electric field, so inductors store energy in the magnetic field. Both capacitors and inductors have many uses with time-varying currents. If you slow or stop the current through an inductor there is a response which works against the change; see Lenz'' Law, $endgroup$

How does an electromagnet switch work?
These switches consist of an electromagnet and a set of contacts that can be opened or closed by the magnetic field generated by the electromagnet. When an electric current passes through the electromagnet's coil, it creates a magnetic field that attracts or repels a movable armature, which in turn opens or closes the contacts.
