An experimental proposal for magnetic system based on the structure of combined coil is presented so as to realize its magnetic drive and control on a micro swimming robot actuated by giant magnetostrictive thin films, as well as to measure its experimental parameters. Firstly the power optimization and design method for the combined coil is introduced, and then a technical approach to ensure the uniformity of its magnetic field is analyzed. Finally, simulation and verification on the combined coil is conducted by means of ANSYS software, and the experimental results show that its performance can meet the expected design requirements for drive and control on the wireless micro swimming robot by magnetic field.
