gradient magnetic fieldRefers to the magnetic field strength with the change of spatial displacement magnetic field strength changes, one-dimensional gradient magnetic field can be expressed by dH/dx. The direction of the magnetic field gradient generally refers to the direction in which the magnetic field gradient changes the most. When dH/dx is a fixed constant, we call it a linear gradient magnetic field. When dH/dx = 0, it is what we often call a uniform magnetic field. The uniform magnetic field can be obtained by using permanent magnet magnetic circuit, electromagnet, solenoid and Helmholtz coil, which is quite extensive in the design and the design is relatively mature.
gradient magnetic fieldThe design of is a more attractive thing. For example, in medical surgery, it is equivalent to an invisible hand controlling the intervention probe to walk according to the specified route and reach the predetermined position for surgery. Control the gradient and magnetic field shape in the magnetorheological polishing grinder to complete multi-faceted polishing, etc. (Hunan Yongyi Technology Co., Ltd. is the magnetic field designer of 7S shell magnetorheological polishing). The following are two gradient magnetic fields designed for users:
