ABSTRACT:
A method of boring a hole through a magnet made of an intermetallic compound, characterized in that the hole is formed by a laser machining. The magnet may be reinforced by impregnation with a nonmagnetic material such as a high polymeric substance or a metal having a low melting point before the hole is bored through the magnet by laser machining.
