1. A magnetic distribution detection method, for detecting the magnetic distribution of a sample, and the method comprising the steps of:
(a) providing a magnetic sensor, and precisely aligning a probe of the magnetic sensor with the sample;
(b) selecting a plurality of measuring points on the sample;
(c) sensing the measuring points by the magnetic sensor, and obtaining a plurality of sense data;
(d) converting the sense data into a plurality of data groups by a signal decomposition algorithm; and
(e) selecting one of the data groups as the magnetic distribution data of the sample;
wherein in the step (c), a plurality of heights from the measuring points are sensed, and the sense datum corresponding to each height is obtained.
