Physics of Magnetism

Magnetism is a fundamental force arising from the motion of electric charges. In magnetostatics, we study magnetic fields created by steady currents or permanent magnets, where charges are at rest or moving uniformly. Magnetic fields influence how objects interact with one another, attracting or repelling depending on their magnetic properties. The behavior of magnets can be explained through concepts like magnetic poles (north and south), lines of force, and the right-hand rule for current. Magnetism plays a crucial role in various technologies, from motors to MRI machines, highlighting its importance in both science and everyday life.
