介绍了如何利用示波器观察和测量铁磁物质的磁滞回线、剩余磁感应强度和矫顽力。

It introduces that how to watch and measure the hysteresis loop-line, residual magnet and coercive force of ferromagnet through an oscillograph.

结果表明，随着磁场的增加，矫顽力及剩余磁感应强度开始时快速增大，高场后增加缓慢并趋于饱和。

The results indicate that as the magnetizing field increases, both the coercivity and remanence increase sharply up to a certain high field and then slowly increase to a saturated value.

随着频率的升高，即使在磁感应强度较低时，涡流损耗和剩余损耗的影响不容忽视，且两者都随温度的升高而升高。

With an increase of the frequency and temperature, the eddy current loss and residual loss contributed to the total loss at the low induction.
