Abstract
In an electromagnetic acoustic transducer or EMAT, a spring release mechanism comprises a frame or carriage and, if necessary at least one movement element for permitting movement across a surface of a workpiece. A magnet is movable against the surface past the frame or carriage and a base supports the magnet. The spring is connected between the frame and the base for biasing the base away from the frame to urge the magnet away from the surface.
