Three-axis Helmholtz coil

Helmholtz coil features a large uniformity volume, greater accessibility to the working gap and easy operation..Helmholtz coil are designed to realize one-axis, two-axis and three-axis magnetic fields, and to provide AC and DC magnetic fields. There is a good linear relation between current and magnetic field. It is suitable for various research institutes, universities and enterprises to do material magnetic characteristic and material measuring experiments. It is applied to materials, electronics, biology, medical treatment, aerospace, chemistry, applied physics and other disciplines. The typical applications include: standard magnetic field generation, Earth’s magnetic field cancellation and compensation, geomagnetic environment simulation, active magnetic shielding effects, electromagnetic interference simulation experiment, Hall Sensor calibration and magnetometers calibration, biological magnetic field study and material magnetic characteristic study. Our coil can be customer-designed according to user’s individual requirements.
