MFG-82 Series Quadrupole Coils
Description:The MFG-82 series quadrupole coils, unlike quadrupole electromagnets, produce a magnetic field that has good linearity with the current, making them easier to control. This device can generate various types of magnetic fields depending on the operation and configuration, such as DC uniform fields, gradient fields, rotating fields, and alternating fields. It is suitable for research institutions, universities, and corporate R&D centers for studies on hysteresis, magnetic susceptibility measurement, Hall effect, magneto-optical experiments, nuclear magnetic resonance, magnetic measurements, magnetic material orientation, spin magnetic resonance demonstrations, and biological research.

Product Features

  • This device can generate various types of controllable magnetic fields through different wiring and excitation methods, as follows:
  1. Wiring opposite coils with the same polarity produces a uniform magnetic field in the central region;
  2. Wiring opposite coils with opposite polarity produces a gradient magnetic field in the central region;
  3. Applying AC current to any pair of opposite coils generates an alternating magnetic field in the central region;
  4. Applying AC currents with a 90° phase difference to two pairs of opposite coils generates a rotating magnetic field in the central region;
  • The housing and frame are made of non-conductive materials for insulation, ensuring safe use;
  • The device can be optionally equipped with an iron core to enhance the magnetic field in the central region, but this increases the power load under AC excitation and may cause nonlinearity between the excitation current and the magnetic field.
  • All parameters can be flexibly customized according to user requirements.
