The metal claws are magnetized when the corresponding coil is energized, creating the north and south poles affecting the smooth permanent magnet rotor. This latter rotor’s magnet has a total of ...

Sometimes the magnetic North Pole and South Pole do switch places. So how does the shifting of these fields differ from the flip? To put it plainly, the shifting happens over the course of ...

British explorer Sir James Clark Ross discovered the magnetic north pole in 1831 in northern Canada, approximately 1,000 miles (1,609 kilometers) south of the true North Pole. We now know that ...
