Abstract
The effect of a DC magnetic field on the rotation of Fe77.5Si7.5B15 and Co7 5Si10B15 amorphous wires under an axially applied AC field is investigated, The rotation frequency mainly decreases monotonically with increasing the DC field. Experimental results are exploited to propose a new family of fie ld positioning microrotor sensors.
