There are a lot of different branches to physics, one of those branches is electromagnetism. Electromagnetism is the interaction between electric currents and magnetic fields or simply just the connection of electricity and magnetism. Electromagnetism was discovered in 1820 by a scientist named Hans Christian Oersted. Oersted was holding a compass near a magnet and he realized that the needle in the compass was not pointing north then later did more research and he discovered electromagnetism. One of the most helpful pieces of research on electromagnetism was done by James Clerk Maxwell, Maxwell had published the Maxwell Equations which were equations on how to solve electromagnetism. Electromagnetism is a type of physics, physics is any science that involves matter, energy, science, or force. Mechanics is a another branch if physics that deals with motion, forces, and statistics and kinetics. There are a lot of different points and parts to electromagnetism.

Electricity has positive and negative charges; the force gets weaker as one get farer from the source and stronger as one get closer. Magnetism works in a similar way with north and south poles. At first, the early physicists thought these two forces as two separate and distinct phenomena. Then, during a demonstration, H. C. Oersted, a Danish scientist, noticed that electric currents caused the needle of a nearby compass to move. Other scientists began to wonder if magnet can create electricity too and Michael Faraway proved it would in a classic experiment, which moving magnet produced electric currents. Faraway wanted to develop the new effects, but his insufficient in math became an obstacle. Then in mid-19th century, James Maxwell, after read Faraway’s work, decided to translate it into the mathematical language and succeeded. Maxwell worked on the equation for electromagnetic waves and fo...
