In the absence of a nearby metal object

Reference no: EM13646908

In the absence of a nearby metal object, the two inductancesL_A and L_B in a heterodynemetal detector are the same, and the resonant frequencies of thetwo oscillator circuits have the same value of 500 kHz. When thesearch coil (inductor B) is brought near a buried metal object, abeat frequency of 4.3 kHz is heard. By what percentage does theburied object reduce the inductance of the search coil?
