Detection of Vibrations in Metallic Structures Using Small Passive Magnetic Fields.

Abstract

An experimental method is discussed for detecting vibrations of metal structure using magnetic fields. The theory assumes that the metallic structure acts as an antenna either through some small residual magnetization in ferromagnetic structures or through induced eddy currents. The detector consists of a noncontacting passive inductance coil.
