A Metal Detector With Two Coils An Exciter And A Detector Is An Example Of An Active Detection System Suppose A Metal 1 (29.24 KiB) Viewed 22 times

A metal detector with two coils (an exciter and a detector) is an example of an active detection system. Suppose a metallic coin (which is non-magnetic on its own, but can have a magnetic field induced by an exciter coil) is lost under the sand at the beach. Part A The exciter coil would use electric current. The detector coil will detect a signal from the lost coin under the sand because O —дфв $E.a1 = an AC, at O an AC, $B-al = (I + cooled o O GE.al = – афв a DC, at o $ B •əl = Ho(I + cool a DC,
