The new Schwartzbeck model HHS 5204-36 Helmholtz-coils are especially designed to generate precisely defined magnetic fields from DC to the upper end of the audio frequency range and beyond to 500 kHz. The generated fields are in a strongly linear relation to the coil current.
The field strength can be calculated exactly by analytical (or numerical) methods, based on the coil’s geometry, the number of turns and the coil current. Therefore the HHS 5204-36 is ideally suited for the calibration of magnetic field probes or sensors.
Due to the use of high temperature proof Teflon wire it is possible to generate magnetic fields up to approx. 3000 A/m for short times. Typical applications are magnetic immunity testing according to automotive standards or MIL STD 461.
