Title:

MAGNETIC CIRCUIT, AND METHOD OF ADJUSTING THE SAME

Document Type and Number:

Japanese Patent JP2014130864

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a magnetic circuit capable of variably adjusting characteristics while consuming very little power, and a method of adjusting the same.SOLUTION: A magnetic circuit 2 comprises, as a characteristic adjustment part 10: a soft magnetic body 11 configuring at least a part of the magnetic circuit 2; a hard magnetic body 12 arranged at a position where a magnetic field can be applied to the soft magnetic body 11; and coils 13a and 13b for remagnetizing the hard magnetic body 12. A current for remagnetization is supplied to the coils 13a and 13b.
