Abstract
The present disclosure provides a method for producing a magnetic powder and the use of a waste magnetic material for producing isotropic or anisotropic magnets. The method including providing a waste magnetic material including a waste magnetic chemical composition, analyzing the waste magnetic material to obtain information about the waste magnetic chemical composition thereof, adjusting the waste magnetic chemical composition to a target magnetic chemical composition to obtain an adjusted waste magnetic material, and atomizing the adjusted waste magnetic material to obtain the magnetic powder.
