For more details see ICNIRP's Guidance on determining compliance of exposure to pulsed fields and complex non-sinusoidal waveforms below 100 kHz. Published June 6, 2012	B and H both describe the magnetic field. The quantities B and H are related to each other by the magnetic permeability (µ) of the medium that they exist in. B=µH, where µ is the magnetic permeability. For air and human tissues µ is approximately 4π x 10^-7 H/m.
