Define and explain magnetism.

Magnetism is a fundamental physical phenomenon that causes certain materials to experience an attractive or repulsive force when placed in a magnetic field. It arises from the movement of electric charges, specifically the motion of electrons within atoms. This phenomenon can be observed in various materials, such as magnets, the Earth’s magnetic field, and electromagnets. … Read more
