The three-dimensional Helmholtz coil magnetic drive system designed by Dexinmag company can be controlled in a closed-circuit manner in the frequency range of 0-20Hz and the magnetic field range of 0-200Gs, and can produce AC and DC uniform strong magnetic field, gradient magnetic field, and rotating magnetic field. Case study The X and Y axis coils are charged to form a 90-degree orientation angle, and the magnetic field can rotate; There is a conductor inside, and the conductor will rotate when it conducts magnetism. Introduction to three-dimensional Helmholtz coils, rotating magnetic field, and gradient magnetic field A three-dimensional Helmholtz coil is a magnetic field generator composed of three coaxial toroidal coils. This coil design produces a uniform and controllable magnetic field, characterized by a magnetic field whose strength remains constant in space. By adjusting the current and geometry of the coil, we can achieve precise control over the strength and direction of the magnetic field. Three-dimensional Helmholtz coils are widely used in magnetic field experiments, magnetic resonance imaging and other fields. Rotating magnetic field refers to the phenomenon that the direction of the magnetic field changes periodically in space. By introducing AC power into a three-dimensional Helmholtz coil, we can achieve the generation of a rotating magnetic field. Rotating magnetic field have many applications. For example, in the study of magnetic properties of materials, rotating magnetic field can be used to change the magnetic behavior of materials, thereby achieving control of material properties.
