In the head of the metal detector is a coil, that is part of an electronic circuit.
The presence of metal causes the frequency of the signal in the circuit to change, setting up an audible note in the headphones worn by the user.
The addition of metal halide gases results in higher light output, more lumens (unit of luminous flux) per watt, and better color rendition than from mercury gas alone.

The purposeful corrosion of a less desirable metal so that an adjacent preferred metal can be protected from corrosion.
