In this letter, we have proposed a new theory on mechanism of the magnetoacoustic (MA) signal generation with magnetic induction for an object with an arbitrary shape. An object under a static magnetic field emits acoustic signals when excited by a time-varying magnetic field, and the acoustic wavef...
