Electromagnetic Induction
1) Allows use to generated electrical power.
2) Allows use to use TV, Radio, cell phones.
3) Gives us light to see by.
4) protects the earth from CME from the sun
5) Gives us a magnetic north and south
6) Allows us to transform energy to different voltage levels
7) Used to make solenoids and electromagnets
8) Helps to cause the northern lights
9) Is responsible for geomagnetic ground currents
10) Use for MRI imaging
11) Allows us to create and use particle accelerators
Without electromagnetism, there would be no electric motors, relays or contractors Everything would have to be driven by internal combustion engines or steam engines; the world would be very different.

Tape Recorder
When a Mylar tape covered with fine iron dust passes near a small electromagnet that has a varying magnetic field, according to an electrical signal, the dust become magnetized in different directions. The electrical signal could be from a radio or microphone. The tape then is a record of the electrical signal. When it passes by another small electromagnet, it creates an electrical signal, duplicating that of the original signal. This signal can be amplified and played back through loudspeakers.
Doorbell Ringer
An old-fashioned doorbell used an electromagnet that was rapidly turned on and off to pull a clangor against a bell.
Loudspeaker
The loudspeakers in your radio, television or stereo system consists of a permanent magnet surrounding an electromagnet that is attached to the loudspeaker membrane or cone. By varying the electric current through the wires around the electromagnet, the electromagnet and the speaker cone can be made to back and forth. If the variation of the electric current is at the same frequencies of sound waves, the resulting vibration of the speaker cone will create sound waves, including that from voice and music.
