PROBLEM TO BE SOLVED : To provide a bond magnet that is used as a gap material of a direct current reactor and capable of reducing the noise of the direct current reactor, and the direct current reactor using the bond magnet.
SOLUTION : As the bond magnet to be disposed in a gap formed in a magnetic core of the direct current rector, the bond magnet containing magnet powders containing the rapidly quenched powder of a rare earth magnet alloy is used. The rare earth magnet alloy may preferably be at least one member selected from a R-X1-X2 magnet alloy (wherein R is at least one rare earth element selected from Nd, Pr, Dy, Tb, and Ho, X1 is at least one element selected from Fe and Co, and X2 is at least one element selected from B and C), a Sm-Fe-N magnet alloy, and a Sm-Co magnet alloy.
