A magnetic air core apparatus that includes a first toroid formed of a plate like structure wrapped in a helical shape and including an air core, further the plate like structure has an outer peripheral surface and an inner peripheral surface, a second toroid that substantially envelopes the first toroid in a concentric manner. The first and second toroids have a first air gap provided therebetween. A start terminal is connected to the first toroid and a return terminal is connected to the second toroid, the start and return terminals enable connections to other electrical devices.
