Demagnitizing
|
Restoration of magnitized jews harp.
Jews harps, in which both the frame and the tongue can be magnetised, after a prolonged exposure to a magnetic field (for example, using a magnetic weighting agent), begin to produce a strange sound. The softer the tongue and the smaller the amplitude of its stroke (volume), the stronger it is heard.
