Square Helmholtz Coil
The Square Helmholtz coil features a large homogeneity volume and a wide magnetic field working gap. The square coil is generally used for testing the large-sized sample, and the side length of the coil can reach 1 meter or even several meters, and it can be designed as the single-axis, two-axis or three-axis coil. The square coil is applied for Standard Magnetic Field Generation, Offset and Compensation of the Earth's Magnetic Field, Geomagnetic Environment Simulation, Judgment of Magnetic Shielding Effect, Electromagnetic Interference Simulation Experiments, Calibration of Hall Sensors and Magnetometers, Biological Magnetic Field Studies and Material Magnetic Characterization studies. Our Square Helmholtz Coil can be customer-designed and customer-made according to the user’s individual parameter requirements.
