PURPOSE: An apparatus for measuring a distribution of a magnetic field is provided, which rotates a ring type magnet by the certain angle using a motor and then precisely measures a distribution of a magnetic field on a circumference of a circle. CONSTITUTION: An apparatus comprises a jig(110) for accepting a ring type magnet(170); a rotating unit(120) for rotating the jig(110) as much as a certain angle for each unit time; a magnet force measuring unit(130) formed on the circumference of a circle for measuring a magnet force of the ring type magnet(170) by a certain time; a magnet force analyzing unit(14) for analyzing the distribution of the magnet force of the magnet(170) according to a certain rotation angle by the measuring signal measured by the magnet force measuring unit(130); a magnet fixing cap(150) for uniformly maintaining the measuring pressure of the ring type magnet(170); and a pinch cap(160) for fixing/separating the jig(110) according to the rotation unit(120). Therefore, the measuring precision is improved and the intensity of the magnet field in a plurality of the ring type magnet(170) is quickly measured.
