Magnets in use process, because of all kinds of conditions lead to a strong magnet magnetic weakening.
Lead to a strong magnet cannot reach the requirement of magnetic production demand, then we should be how to strengthen the powerful magnet magnetic?
You first need to understand, from the Angle of the magnet itself, powerful magnets to increase magnetic, unless it is not saturated magnetic, or because by various factors in the process of using,
Current, intense vibrations, temperature)
Influence of demagnetization, otherwise it is not possible in the increase of the magnetic.
Increase magnetic ways mainly have the following kinds: 1, the magnetic circuit design method of the magnetic flux gathering in yoke iron to produce strong suction.
Can also need not able 2, magnetic force is not enough, another wall in magnets and iron to strengthen the magnetic force, the magnet is used in the noodles.
3, the short answer way we can restore the magnets for magnetic, to the state of saturation magnetization.
4, can adopt the method of concentrated magnetic field lines, in a strong magnet suck on a piece of magnetic iron plate, on the edge of the magnetic iron plate edges and produces higher magnetic fields.
A: what are the considerations for using powerful magnets?
Next: what are the scope of ndfeb magnets used?
