Induction Balance Discriminating Metal detectors with Arduino

An Induction Balance (IB) metal detector has a transmit and a receive coil. The coils are arranged so that, with no metal present, the coupling cancels out to zero in the receive coil. For conductive objects, eddy current induced in nonferrous metals repel the AC magnetic field, causing the receiver coil to no longer be nulled.
