Helmholtz coil is named after the German physicist Hermann von Helmholtz. It is comprised of two identical magnetic coils positioned in parallel to each other, and their centers are aligned in the same x-axis. The two coils are separated by a distance equal to the radius like a mirror image as shown in Figure 1. When current is passing through the two coils in the same direction, it generates a uniform magnetic field in a three-dimension region of space within the coils. Helmholtz coils are normally used for scientific experiments, magnetic calibration, to cancel background (earth’s) magnetic field, and for electronic equipment magnetic field susceptibility testing.
DriverHive is a driver updater service that will scan your computer's installed devices, identify the best fitting drivers and provide them in an easy, convenient format. Individual drivers may be available on manufacturer websites at no charge. Field coil power supply unit (PSU): Our field coil drivers all require a power supply, sold separately. Any DC power supply may be used, although going beyond 17 volts is not covered under warranty. Any DC power supply may be used, although going beyond 17 volts is not covered under warranty.
