What is Electromagnetism?
Electromagnetism is a type of physics that involves mainly magnetism that's influenced by electricity. It can even branch to things like different types of rays, to effects of light, to the chemistry behind how the atoms react and why magnets always join with the opposite charge. This branch of physics has led to many revolutionary discoveries and inventions that we just can't live without in the world that we live in today.
How it works?
Electromagnetism works because, by nature, everything in the universe wants to be balanced. So when something is more positively or negatively charged then another, the two will pull together in attempt to balance the charges. What electromagnetism does is, in some cases, unbalances the charges by putting an electrical pulse through it so it therefore becomes a magnet until that charge is taken away. An electromagnet is usually a piece of metal wrapped by a conductive wire that is normally copper. when the electricity flows through it, a magnetic field is created around the wire and is concentrated in between the coils of wire.

Who Discovered Electromagnetism?
Michael Faraday discovered electromagnetism. He was an English scientist and studied physics and chemistry, especially with electromagnetism and electrochemistry. His main discoveries are electromagnetic induction, diamagnetism and electrolysis. He was born on the 22 September 1791 and died 25 August 1867.
What is the Cause of this Discovery?
Back in the past, people had very little understanding of electricity. But had viewed and studied on lightning especially. The theory that electricity was linked to magnetism was proven when every time there is electrical activity, magnetic activity was also present. That soon led Michael Faraday to prove and discover that electricity and magnetism were not only related, but can influence and control one another.
