Abstract: Disclosed are a pulse magnet device based on magnetic flux compression, and a high-flux measurement method. The device includes a diamagnetic block, reinforcing plates, screw rods and a magnet coil. The diamagnetic block and the magnet coil are concentrically arranged in the axial direction; the reinforcing plates are arranged at ends of the magnet coil and the diamagnetic block and are connected by means of the screw rods. The diamagnetic block is used for inducing the induction current opposite the coil current during the discharge of the magnet coil, and for compressing the magnetic field to the area between the diamagnetic block and the magnet coil. The intensity and uniformity of the magnetic field around the magnet coil are improved by means of increasing the magnetic flux density.

Abstract: The present invention belongs to the technical field of magnetically controlled soft-bodied robots, and more specifically, relates to a controllable and reconfigurable magnetization system and method for a magnetic soft-bodied robot. The system comprises a pulse power supply module, magnetizing coil units axisymmetrically arranged up and down, and a magnetic soft-bodied robot placed between the upper and lower magnetizing units. By means of changing the relative current flow direction of the upper and lower magnetizing coil modules, radial and vertical magnetic fields can be generated between the magnetizing coils arranged oppositely without any mechanical movement, so that the internal magnetization direction of the magnetic soft-bodied robot can be configured simply and flexibly. The present invention realizes for the first time the particle magnetization and synchronization of bidirectional orientations, and decouples the material preparation process of the magnetic soft-bodied robot from the magnetization process, so that the entire manufacturing process is very simple. Moreover, the internal magnetization distribution is reconfigurable, which provides a completely new technical approach for realizing multifunctional magnetic soft-bodied robots.
