Description:The MFG-11 series 1D circular Helmholtz coils generate a uniform magnetic field at the center when excited by a power supply. They offer a large uniform field volume, spacious working area, and easy operation. Configurable for 1D, 2D, or 3D combined magnetic fields, supporting both AC and DC fields with excellent linearity between field and current. Ideal for research institutes, universities, and enterprises conducting magnetic property measurements or detection experiments. Applications span materials science, electronics, biology, medical, aerospace, chemistry, and applied physics. Primary uses include generating standard magnetic fields, canceling/compensating Earth's magnetic field, simulating geomagnetic environments, evaluating magnetic shielding effectiveness, electromagnetic interference simulation, calibrating Hall probes and magnetometers, studying biomagnetic fields, and investigating magnetic properties of materials.
