Electromagnetic Induction

When an electric current produces magnetic fields, the idea of magnetic fields producing electric currents came up, thus creating a conducting loop called induction.

Michael Faraday

In 1831, Michael Faraday made the revolutionary discovery of electromagnetic induction which explained the reasoning behind electricity and the way it flows through conductors and generators. The discovery of this opened many doors into the world of new technology. For the remainder of the decade, he continued to expand his study on electromagnetic induction and is partially responsible for coming up with terms such as, "electrode", "cathode", and "ion".

5 Ways Electromagnetism Has Improved Our Lives

1. When it comes to locking our homes and securing safes, etc. there are magnetic locking devices that are used by most people. They are either unlocked by the use of a number code or a magnetic card in which the numbers are kept on file in the magnetic tape on the back of the card and when swiped, they are matched and it opens.

2. The use of memory storage devices such as flash drives or memory sticks can contain milligrams of information and save us the hassle of carrying around text books all of the time. The data is stored in an electromagnetic format.

3. Communication devices such as telephones take a huge role in electromagnetism; the interaction between the electromagnetic pulses and the signals make cell phones capable of power.

4. Another common example of electromagnetism that humans often encounter and may not think twice about is the use of doorbells. When the button is pushed, the coil becomes energized which activates the electromagnetic forces and sounds the bell.

5. The electric fan in nearly all homes operates under the electromagnetic induction principle which causes the rotation of the blades, thus blowing air.
