When like poles of a magnet are brought together, they repel each other. Magnets possess two poles: North and South. According to the principles of magnetism, like poles (North-North or South-South) experience a repulsive force. This occurs because the magnetic field lines generated by the like poles push against each other, leading to a force that pushes the magnets apart. This property is fundamental to understanding how magnets interact with one another and is crucial in various applications, such as magnetic levitation and electric motor design. The repulsion contrasts with the behavior of unlike poles, which attract each other due to the interaction of opposite magnetic fields.
