[ We claim:] [1.] A method of operating an inductor comprising an electrically conductive induction coil having therethrough a passage and having opposite ends, said method comprising:inductively coupling said coil to an electrically conductive component during a first working phase while cooling said coil by a fluid;reducing said coupling during another working phase while cooling said coil to a different extent than during said first working phase; andsaid cooling during at least one of said phases additionally comprising withdrawing heat from said electrically conductive component by passing said fluid through said passage by supplying said fluid to both said ends, and discharging said fluid from a middle portion of said coil located between said ends.
