[0003] In order to obtain a magnetic field with good uniformity, most conventional magnetic field generating devices are based on the magnetic effect of current. Chinese patent (a magnetic field generating device, CN 207834046U) discloses a device that utilizes an electromagnet to generate a magnetic field, but the magnetic field The direction of the magnetic field obtained by the device is specific, which cannot meet the needs of some multidimensional magnetic field direction experiments

Part of the magnetic field device can obtain a direction-variable magnetic field by applying a rotating device. A Chinese patent (a 360° rotatable electromagnetic field device, CN 204045315U) proposes a 360° electromagnetic field device for magnetic experiments. The connecting shaft drives the rotation of the magnetic field device, but it can only realize the rotation of the magnetic field device in the horizontal plane; the Chinese patent (a rotating magnetic field device, CN106693817A) proposes a device that controls the rotation of the electromagnetic field through the rotating system, but it can only realize the rotation of the vertical magnetic field direction. Circular rotation motion; Chinese patent (a rotating magnetic field generating device, CN106693817A) proposes a rotating magnetic field generating device for magnetic carrier separation technology, which drives the magnetic field generating structure to rotate at a certain speed through a power device, but can only generate The effect of the magnetic field rotating in the radial direction, none of the above devices can achieve the effect of a three-dimensional magnetic field
