What are Electromagnets?
Electromagnets generate a magnetic field without relying on mineral-based magnetic materials. Instead, they use alternating or direct electric currents flowing through copper coils to produce magnetism. Once the power supply is switched off, the magnetic field disappears.
This ability to control the magnetism by simply turning the power on or off is highly beneficial in many industrial applications. However, because electromagnets require an active power source, they are not classified as permanent magnets as they can be activated and deactivated at will.
