Time-Varying Magnetic Field Produced by a Vibrating Aluminum Enclosure

Abstract

Circuit theory is applied in the determination of the time-varying axial magnetic field produced by the interaction of a vibrating aluminum enclosure and the earth's magnetic field. The axial magnetic field that exists within the enclosure is received by a loop antenna. A steady-state time-harmonic analysis is applied. Theoretical results are compared with measured data at 100Hz.
