An electric induction heating and melting system is provided for inducing heat in an electrically conductive material placed in a containment vessel by bringing a moveable one or more induction coils at least partially enclosed in a refractory material in close contact with the surface level of the melt in the vessel while supplying ac power to the one or more induction coils. The moveable one or more induction coils can be kept in close contact with the surface level of the melt as the height of the melt in the vessel changes.
