The dynamic magnetic field generated by the electromagnetic coil is mainly the uniform magnetic field generated by the Helmholtz coil and the uniform magnetic field generated by the Maxwell coil. The method of attitude adjustment realizes the control of the shape and motion of the micro-robot, but due to the limitation of the electromagnetic field, the magnetic field space generated by it is small, and the space for the micro-robot to move is small

When a single permanent magnet is used to achieve control, the magnetic field strength generated by it can stabilize the operated object. For example, the document "Control of Untethered Magnetically Actuated Tools using a Rotating Permanent Magnet in any Position" proposes a permanent magnet through rotation The method of forming a rotating magnetic field to drive the tool to rotate can be found from the experimental process that the manipulated permanent magnet can rotate close to the surface of the workpiece stably and at a high speed. It can ensure the rotation on the surface of the workpiece, and cannot achieve complete suspension rotation
