Electro-magnetic Extravaganza

Electromagnetic Induction in Motors and Generators

Motors and generators are essentially the same thing. A motor uses electromagnetic induction to convert electrical energy into mechanical energy. To do so, a current is passed through a coil of wire that is surrounded by a magnetic field. The interaction of fields causes the coil to spin, creating mechanical energy. A generator works in reverse. Magnets are spun around a coil of wire to induce a current in the wire by changing the magnetic field constantly.

Improving Lives

There are countless ways that humans have used electromagnetism to improve their lives. Some examples of these improvements include: microwaves, credit card readers, hard drives, microphones, VHS tapes, and speakers.
