Title: Magnet type medical instrument and electromagnet and coil used in it

Abstract: The purpose of the present invention is to propose a magnet type medical instrument which can prevent the magnetic flux density from reducing remarkably even at a point distant from a magnetic pole of a core and realize a satisfactory pain-killing effect in a human body even at a point distant from the magnetic pole. The electromagnet for the magnet type medical instrument comprises a first core 1 with first inner space and a first coil 3 which is wound round the first core 1 and which can generate a first magnetic field by applying an alternating current, a commutated current or a pulsating current to the first coil 3.
