Ferrite Disc Magnet Ø15x3mm Pull Force 180gr

Ferrite disc magnet. Magnets usually have the North (N) and South (S) poles on their flat circular surfaces and feature axial magnetization. Ideal for souvenir items, ceramics, plastic, paper, wooden, and other refrigerator items. The magnetic compass is the most well-known type of compass. It works as an indicator of magnetic north, the local magnetic meridian, because the magnetized needle at its core aligns with the horizontal component of the Earth's magnetic field. The magnetic field exerts torque on the needle, pushing the north end or pole of the needle approximately toward the Earth's north magnetic pole and pulling the other end toward the Earth's south magnetic pole. The needle is mounted on a low-friction pivot, while in better compasses it is mounted on a bearing so that it can turn easily.
