Abstract
The present invention discloses an electromagnetic device which includes a magnetic flux producing apparatus for producing a magnetic flux path loop. The magnetic flux producing apparatus preferably comprises a magnetic core 20 surrounded by electrical windings 22. A strip of electrically conductive material 24 is disposed such that it passes through the magnetic flux path loop and overlies the windings 22. The strip 24 has a width which is substantially greater than its thickness. The device may further include an antenna 16 which is electrically coupled to the strip 24.
