Abstract
Magnetic fields may alter the flexural resonant frequencies of vibrati ng reeds that possess anisotropic magnetic susceptibility. The magnitu de of the effect is a quadratic in the field strength. It is also a fu nction of field orientation, the reed's aspect ratio and Young's modul us, the vibrational mode, and the magnetic susceptibility tensor. This phenomenon can provide a direct and extremely sensitive measure of ma gnetic anisotropy.
