摘要:
A small magnetostriction gauge is described which can be used for the comparison of supersonic intensities. The gauge consists essentially of a small rod of nickel wound with a few turns of wire. The acoustic pressures present in the liquid produce changes in length of the rod which in turn, because of the inverse magnetostrictive effect, induces voltages in the coil.
