Handheld Metal Detectors a Comprehensive Guide to Technology

Indeed, handheld metal detectors utilize electromagnetic induction to detect metal objects. These devices generate a magnetic field by passing an electrical current through a coil of wire. When a metallic object enters the magnetic field, it disrupts the field, causing a change in the electromagnetic field detected by the detector’s receiver coil. This change triggers an audible or visual alert to notify the operator of the presence of metal. https://www.novusapl.com/Handheld-Metal-Detectors-Comprehensive-Guide.php
