Power frequency magnetic field immunity

Introduction：

Industrial frequency magnetic field immunity test is a kind of IEC61000-4-8, GB/T 17626.8 defined by the demand for industrial frequency magnetic field test and build the test project, electronic products may be affected by the magnetic field generated by other equipment, and they all work in the industrial frequency 50Hz or 60Hz. so it should be used in the industrial frequency of the sinusoidal waveform to carry out the magnetic field experiments.

Source of the industrial frequency magnetic field:

The standard defines an industrial frequency magnetic field as being generated by industrial frequency currents in other conductors or, to a very small extent, by other devices in the vicinity (e.g., leakage flux from a transformer).
