Measurement of high-frequency magnetic field distribution of square coil based on projection method

This paper proposed the measurement of high-frequency magnetic field distribution of square coil based on projection method. Conventional one turn search coil was developed in array in order to used as magnetic field distribution probe. The probe was rotated over a magnetic field measuring area to obtain projection magnetic field distribution. Reconstruction of magnetic field distribution can be achieved by applied back projection technique to measurement data. The results are discuss and compared with the calculation both analytic solution and finite element analysis.
