© 2017 IEEE. The rotating magnetic properties of nanocrystalline materials at high frequencies play an important role in design and optimization of high frequency transformers with large capacity and high performance. In this paper, a novel high frequency rotating magnetic properties tester is designed, which is applied to measure the high frequency rotating magnetic properties of nanocrystalline materials. By changing the shape of the core, a new magnetic circuit structure is designed, which reduces the difficulty in assembly of the magnetic cores and improves the stability of the test system. A layer winding with copper foil is designed to ensure the accurate simulation of the high frequency rotating magnetic field. The influence of sample size and winding position on excitation effect is analyzed by finite element simulation. The magnetic circuit structure is optimized and the feasibility of the scheme is verified.
