Abstract :
Magnetic noise in tape cores can in general be suppressed considerably by passing suitable galvanic currents through them. The method is also applicable to samples subject to asymmetric shear twist forces. A linear decrease in peak-to-peak maximum magnetic noise is observed for increasing currents through the core for the amorphous ribbon Fe80B20.
