All About Electromagnetics

How does an electromagnet work?

• They transfer energy

• They eat food to gain energy

• They need a electric current to become a magnet

• They absorb energy and transfer it

What is Electromagnetic Induction?

• a solenoid with a ferromagnetic core

• Information sent as patterns of electromagnetic waves

  EX. visible light, infrared waves, microwaves, and radio waves

• Energy that can travel in form of waves or all objects in space give off energy

• The process of generating an electric current from the motion of a conductor through a magnetic field

Cause and Effect : Electromagnetism

• Cause: Forces occur between any two charged particles

• Effect: Resulting in the electrons being able to move

• Cause: In metals there are many electron energy levels near the Fermi level

• Effect: Resulting in attraction between opposites and repulsion between same charges
