Conversion of Mechanical Energy into Thermal Energy
Permanent magnets - Applications and perspectives

The conversion of mechanical energy into thermal energy using induced currents has become widespread with the commercialization of induction ovens and cooktops. However, many other applications—often less well known to the general public—utilize these same currents, which can sometimes cause unwanted heating.

Consider the diagram in Figure 24 , where the driven part is no longer a magnet, as in Figure 22 a, but a circular disk...
