Circular Helmholtz сoil HHS 5202-81 is ideally suited for the calibration of magnetic field probes or sensors. Due to the high temperature proof Teflon-coated wire packet it is possible to generate magnetic fields up to approx. 3000 A/m (for a short time).
Typical applications are magnetic immunity testing according to automotive standards or MIL-461G.
