磁场的强度，为在强磁性的物质达到饱和之后，把它的磁化作用缩小到零所必需。
The intensity of the magnetic field needed to reduce the magnetization of a ferromagnetic material to zero after it has reached saturation.
在靠近磁场时，磁场强度达到50 - 100高斯，对铁磁性物质产生强吸引力。
Strong attraction of ferromagnetic objects may occur at close distances to the magnet, where the magnetic field is above 50 to 100 gauss.
