Claim:
1. An apparatus comprising: a permanent magnet that provides magnetic flux; an electric field generator comprising: at least one conductive loop, a first portion of an ellipsoidal shell formed by a low permeability material that is configured to direct a first portion of the magnetic flux through a first portion of the at least one conductive loop, and a second portion of the ellipsoidal shell formed by a high permeability material that is configured to direct a second portion of the magnetic flux through a second portion of the at least one conductive loop, wherein the second portion of the magnetic flux is greater than the first portion of the magnetic flux; and a supporting system configured to support the permanent magnet within and at a distance from the ellipsoidal shell and enable relative movement between the permanent magnet and the electric field generator.
