What is the concept of stray fields in magnetic materials?
The stray magnetic field is related to the demagnetizing field of the magnet surface, which is mainly affected by the state of the surface of the magnet (edges, corners, defects, etc.), which originates from the magnetic dipole interaction between the free magnetic poles of the surface of the magnet.
Stray fields are a weak attraction in a lattice that links neutral molecules or essentially uncharged units.
I understand, probably can use the stray field as the surface magnetic flux density, due to surface defects produced in this way, demagnetizing field, there is a difference and the strength theory of saturated magnetization, minus the demagnetizing field results of the stray field is the theoretical value, is the actual surface of the magnet flux density.
