Magnetic Dipole

A magnetic dipole is a fundamental concept in magnetostatics, describing a system that has a north and south pole, similar to a bar magnet. It generates a magnetic field around it, with field lines emerging from the north pole and returning to the south pole. When placed in an external magnetic field, a dipole experiences torque, aligning itself with the field. Magnetic dipoles can be found in atoms due to circulating electric currents, making them key to understanding magnetism in materials and devices like motors and compass needles. Their behavior helps explain how magnets interact with each other and with electric currents.
