loops by the removal and reapplication of magnetic force. In these operations the 
behaviour of the model agrees in all respects with that of a magnetic metal.

The same close correspondence is found even in less obvious features of the 
magnetizing process. This is illustrated in figs. 38, 39, and 40.
