Alien magnet manufacturer introduce magnet divided into two types: permanent magnet and electromagnet magnet is divided into two types: permanent magnets and electromagnets.
The two kinds of magnet magnetic strength can size is different.
For permanent magnets, is the main reason of the weak magnetic properties of magnetic materials.
Magnetic materials have magnetic characteristics curve (
If the substance of the hysteresis loop area is large, coercive force is big, remanence is big, strong magnetic.
Another case is matter of hysteresis loop is long and thin strip, very easy to demagnetization.
Special-shaped magnet magnetic strength is mainly rely on outside the core coil number of turns and the current strength.
The coil number of turns, the more by the current intensity, the greater the it the stronger the magnetism.
Process knowledge: electromagnet is iron wire tube, special-shaped magnet magnetic strength related to the electric current.
The working principle of electromagnet is the use of biot
The sand tile's law and kirchhoff's law carries on the magnetic field design and calculation.
