MFG-81 Series Maxwell Coils

Description：The MFG-81 Series Maxwell Coils, compared to Helmholtz coils, can generate a larger uniform magnetic field in the central region with better uniformity when excited by a power supply. They offer ample working space and are easy to operate. Capable of producing both AC and DC magnetic fields, the generated field has good linearity with the current. Therefore, in applications requiring highly uniform magnetic fields or more compact coil volumes, Maxwell coils are preferred. They are suitable for research institutes, universities, and enterprises for material magnetic property testing or detection experiments, applied in fields such as materials, electronics, biology, medical, aerospace, chemistry, and applied physics. Main uses include generating standard magnetic fields, evaluating magnetic shielding effectiveness, electromagnetic interference simulation experiments, calibrating Hall probes and various magnetometers, studying biological magnetic fields, and researching material magnetic properties.
