Abstract: An induction coil furnace system includes at least an active induction coil and a passive induction coil surrounding a furnace volume. The active induction coil is connected to an AC power supply, while the passive induction coil is connected in parallel with one or more capacitors forming an L-C tank circuit. The connections to the AC power supply and the one or more capacitors are optionally an interchangeable connection, such that the active coil can become the passive coil upon disconnection of the AC power supply and connection of the one or more capacitors. Likewise, the passive coil can become the active coil upon disconnection of the one or more capacitors and connection of the AC power supply. The active coil is selectively electrically connected to the passive coil via a separable electrical connection, whereupon separation, the active coil and the passive coil are electrically isolated.
