They illustrate how a metal detector transmits a magnetic field via a search coil (TX). When that field passes over a conductive target (a coin, ring, or relic), it induces eddy currents in the target. Those eddy currents generate a secondary magnetic field, which is received by a second coil (RX). The difference—or "imbalance"—is the signal you hear. : Most chapters include functional example designs with

Inside the Metal Detector by George Overton and Carl Moreland is the definitive technical guide for hobbyists and engineers wanting to understand the electronic design behind detection technology. It moves beyond simple "how-to" operation and focuses on the physics of electromagnetism, circuit topologies, and DIY construction projects. ⚡ Core Technical Concepts The difference—or "imbalance"—is the signal you hear
