ABSTRACT:
The present invention relates to a method for measuring three-dimensional spatial magnetic field distributions used particularly in measuring the magnetic field distribution in a small spatial region such as a leakage magnetic field of a magnetic head and the object thereof is a measuring method capable of measuring a high frequency magnetic field in the small spatial region with a high precision.
