... separation between the in-phase and out-of-phase resonant frequencies. Lorentz forces generated by an electric current loop within a permanent mag - netic field excite only the out-of-phase mode. The ... flywheel is minis- cule. Instead, micromachined sensors that detect angular rotation utilize the Coriolis effect. Fundamentally, such devices are strictly angular-rate or yaw-rate sens...
