Screwdriver and pliers, etc., to go to the magnet, what are the methods?
Put it on the floor and throw it several times. The same is to change the direction of the internal magnetic field to achieve the purpose of demagnetization.Magnetism is the magnetism that attracts iron, cobalt, and nickel. The region with the strongest magnetism at either end of the magnet is called the magnetic pole. One end is called the north pole (N pole), and the other end is called the S pole. Experiments show that the same magnetic pole repulsion, unlike magnetic poles attract.
The internal magnet charge movement is the regular arrangement of the charge movement, also produced a field, field and field produces forces, when the magnetic field is generated each moving charge in the same direction, the macro objects showed the magnetic field direction, so that the internal chaos, macro is not magnetic.
