The hysteresis loop of a soft iron piece has a much smaller are than that of a carbon steel piece . If the material is to go through repeated cycle of magnetization , Which piece will dissipate greater heat energy ?

Question

$\begin{array}{1 1} \text{Iron piece will dissipate greater energy } \\ \text{Carbon piece will dissipate greater energy } \\ \text{Both the pieces will proportional to each other } \\ \text{None of the above } \end{array} $
