Abstract：
An experimental method used for determining the magnetisation vector of NdFeB rectangular permanent magnet is described.On the supposition that the individual blocks are magnetized uniformly,this method can give not only the magnitude and direction of the magnetisation vector,but also the offsets between the magnetic and geometric center of the blocks.
