    Sep 13, 2019 The shielding in the primary coil is designed to block the magnetic flux from going down to the metal plate below the floor-board of the garage to cause eddy current loss. The shield is designed to cut-off the magnetic flux in case it goes into the chassis of the vehicle, which may put the humans in danger as well as causing energy loss
