Magnetic Moment

Magnetic moment is a measure of an object's ability to produce a magnetic field, similar to how a tiny bar magnet behaves. It stems from the movement of electric charges, such as electrons within atoms. In materials like iron, these tiny magnetic moments align to create a noticeable magnetic field, like in a magnet. The stronger the magnetic moment, the stronger the magnetic effect. It helps explain why objects are attracted or repelled by magnets and is fundamental in understanding how magnetic forces work in everyday devices like electric motors, compasses, and magnetic storage.
