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.

Operating Principles
The Helmholtz coil consists of a pair of identical circular coils, of which nominal radius is R, and of which the central axes are on the same axis as the Z-axis. The nominal distance between the two coils is h=R. The two coils have the same number of turns, and each of the coils carries the equal current in the same direction, and there is a good linear relation between the current value and the field magnitude.
