Typically sourced from ships (either as part of regular scrapping or shipwrecks ) and other steel artifacts of this era, it is often used for modern particle detectors ...
Variations in the electrical conductivity and magnetic permeability of the test object, and the presence of defects causes a change in eddy current and a corresponding change in phase and amplitude that can be detected by measuring the impedance changes in the coil, which is a telltale sign of the presence of defects.

It involves a metal detector, prodding instrument and tripwire feeler. [36] Deminers clear an area of vegetation and then divide it into lanes. A deminer advances along a lane, swinging a metal detector close to the ground.
