In each case, strong magnet has magnetism in use process becomes less.
Therefore, can not reach the required to produce the strong magnet magnetic requirements, how to improve the strong magnets, magnetic energy?
First of all, it is important to understand, from the point of view of the magnet itself, unless by various factors in the process of using strong magnet (
Severe vibration, current, temperature)
Demagnetization or not by magnetic saturation, otherwise cannot increase its magnetism.
Increase the strong magnet magnetic method: 1.
The easiest way we can restore the magnets for magnetic, to the state of saturation magnetization.
Magnetic circuit design method of the magnetic flux gathering in yoke iron to produce strong suction.
Magnetic force is not enough also need not hair, can add a iron in magnet another wall to enhance magnetic force, the magnet is used in the noodles.
Can adopt the method of concentrated magnetic field lines, suck on a piece of magnetic iron plate on the magnet, on the edge of the magnetic iron plate edges and produces higher magnetic fields.
