PROBLEM TO BE SOLVED: To provide a magnet assembly which forms a uniform magnetic field on a target surface; an instrument for measuring magnetic leakage flux by using the magnet assembly; a method for measuring the magnetic leakage flux; and a testing method.;SOLUTION: The magnet assembly comprises: a means for forming a magnetic field, which includes a pair of magnets; and a base for attaching one or more means for forming the magnetic field to itself. The means for forming the magnetic field comprises: a fixed stand for fixing magnets thereon; and a pair of the magnets which are combined through a spacer. One of the magnets is placed such that a positive pole can face to a fixed stand side and the other magnet is placed such that a negative pole can face to the fixed stand side. When the magnet assembly has 2 or more means for forming the magnetic field, the means for forming the magnetic field are attached onto the base so that the positive pole and the negative pole of the pair of the magnets are linearly aligned in a row. The instrument for measuring the magnetic leakage flux by using the magnet assembly, the method for measuring the magnetic leakage flux and the testing method are also provided.;COPYRIGHT: (C)2008,JPO&INPIT
