By configuring this idea as described above,
Evaporated particles can be removed before the ferromagnetic material reaches a stable heating state, and after the ferromagnetic material reaches a stable heating state, the radiant heat increases the temperature of the liquid that serves as the magnetic fluid medium. This has excellent effects such as being able to prevent an excessive increase in the ferromagnetic material and also preventing bumping of the ferromagnetic material.
