Heebie Jeebies - Metal Detector


This product is unavailable

Make a metal detector that really works for finding treasure in your own backyard. When electric current passes through the wire coil, it creates an electromagnet. When passed through a ferrous(or magnetic)metal, eddy currents are produced in the metal.  This disrupts the magnetic field produced by the coil and causes the buzzer in the detector to go off.
