Physical parameters: ndfeb magnetic hysteresis loop when H is the biggest change to the negative one of the biggest, is one of the biggest again, B -
H or M -
H formed a closed curve, the curve is called hysteresis loop.
Hysteresis loop of some notes: & ensp;
The relationship between the magnetic induction intensity B and H said normal curve, B = J + H 2.
Intrinsic magnetization is called the intrinsic relation between J and H curve & ensp;
Usually with hysteresis loop in the second quadrant to analyze the performance of the permanent magnet, intrinsic curve, normal curve is applicable.
Lower than the Br on the demagnetization curve of a point, known as the working point;
Call a connection line between the working point and the origin of load, expressed as Bd/Hd.
