Abstract :
This paper deals with the extruded radially oriented magnets made from rapidly solidified Nd-Fe-B material. The effect of chemical composition on the magnetic properties and hot workability was studied for various compositions in Nd-Fe-Co-Ga-B system. The composition ranges of Nd and B which shows maximum energy product and hot workability were determined
