Abstract:
The present invention provides a bond magnet for direct current reactor which is to be disposed in a gap formed in a magnetic core of a direct current rector, the bond magnet containing a magnet powder containing a rapidly quenched powder of a rare earth magnet alloy. The present invention also provides a direct current reactor including a magnetic core having a gap and a winding area wound around the magnetic core, in which the bond magnet is disposed in the gap of the magnetic core.
