How do motors use electromagnets
WebAn electromagnet can be defined as a magnet which functions on electricity. Unlike a permanent magnet, the strength of an electromagnet can be changed by changing the amount of electric current that flows … WebLook up a commutator on a brushed DC motor. The brushes changing which contacts they are touching causes different windings in the rotor to be energized. Separate electromagnets are being turned on and off in sequence based on the commutator position.
