Abstract:
1. A method for manufacturing a rare earth magnet comprising the steps of: producing a rare earth magnet sintered body from rare earth alloy powder; and dividing the sintered body into a plurality of rare earth magnets, wherein the step of dividing the sintered body is executed by a method for cutting a rare earth magnet sintered body using a wire with abrasive grains fixed to a core wire, comprising the step of: cutting the rare earth magnet sintered body with the wire traveling in a state that a portion of the rare earth alloy sintered body to be cut with the wire is immersed in a coolant containing water as the main component, the coolant having a surface tension at 25° C. in a range of 25 mN/m to 60 mN/m.
