How Do You Build a Metal Detector

To make a metal detector, take an AM radio and tune it the highest end of the AM radio frequency, but not on a station that is broadcasting. Turn the volume up as loud as possible. The only noise heard should be static. Then, tape a calculator to the radio.

How Do Metal Detectors Work

Metal detectors work by sending and receiving electromagnetic fields. A search coil sends an electromagnetic field into the ground. That field energizes any metal object it contacts, then the object sends an electromagnetic field back up. Once that field reaches the sea
