Multipole Electromagnet

Multipole Electromagnet

product description:

The multi-pole electromagnets independently developed by Beijing Jinzhengmao Technology Co., Ltd. are mostly quadrupole electromagnets, and there are also five-pole, six-pole, eight-pole and other multi-pole applications, mainly used in multi-pole magnetic ring magnetization, radial gradient magnetic field , rotating magnetic field magnetic guidance and other applications, designed and manufactured according to the user's requirements, this type of electromagnet can be completely compatible with the magnetic field platform designed by the customer.

Product Usage:

Electromagnet/electromagnetic field generator is mainly used for hysteresis research, magnetic susceptibility measurement, Hall effect research, magneto-optical experiment, magnetic field annealing, nuclear magnetic resonance, electron paramagnetic resonance, biological research, magnetic measurement, magnetic material orientation, Hall effect Hall effect, permeability measurement, spin magnetic resonance demonstration, biological research, etc.

Product advantages:

※Multi-pole water-cooled or air-cooled, with wide field of vision, high magnetic field strength, and convenient adjustment of magnetic field strength

※Small size, light weight, small duty cycle, compact structure and better magnetic field performance.

※Optional working gap scale indication

※It is used for magnetization of ferrite products and magnetization of magnetic sample products when the air gap is small.

At the same time, it is perfectly combined with the high-precision bipolar constant current power supply and FCP magnetic field control platform independently developed by Beijing Jinzhengmao (stability 10PPM) to form a multi-functional laboratory magnetic field generation system. In this system, fast and uniform magnetic field scanning and magnetic field commutation can be achieved through the output of the true bipolar constant current power supply, thereby avoiding the intermittent problem of zero-crossing inversion when using discontinuous power supplies, and achieving true zero magnetic field.
