Magnetism and electromagnetism are fundamental concepts in physics that govern the behavior of magnetic fields and their interaction with electric currents. Magnetism arises from the motion of electric charges, such as electrons, within materials, creating magnetic fields. Electromagnetism extends this understanding to the dynamic relationship between electric currents and magnetic fields, as described by Maxwell's equations. These phenomena play crucial roles in various applications, from motors and generators to telecommunications and magnetic resonance imaging (MRI).
