Abstract:
The present invention provides a bonded isotropic magnet containing a composition comprising from about 5 to 25% rare earth metal, from about 0.5 to about 4.5% boron, from about 0.5 to about 3.0% niobium, and the balance principally of iron. Such a magnet exhibits low coercivity and low loss upon aging.
