Abstract
A method for evaluating a uniformity of a magnetic field generated by a magnetic coil is disclosed. The method may include providing an electrical current to the magnetic coil to generate a magnetic field; scanning and obtaining a set of signals of the magnetic field by moving a measurement probe of a scanning tool point by point within a scanning region of the magnetic field and at a scanning height; performing a spectrum analysis on the set of signals by a spectrum analyzer to extract spectrum information of the magnetic field; transferring the set of signals and the extracted spectrum information to a computer system; selecting signals of the magnetic field with one or more frequencies from the set of signals based on the extracted spectrum information by the computer system; and analyzing the uniformity of the magnetic field by analyzing the selected signals by the computer system.
