Abstract

An amplifier and a coil are electrically connected to an amplifier in a coil system. A current controller is provided for adjustment of the current which is supplied from the amplifier to the coil. The current controller adjusts the current such that, at least on average, a predetermined power loss is converted to heat in the coil.
