The magnetic field monitoring loop FESP 5133-7/41 was designed to measure magnetic fields in the frequency range up to 200 kHz. The coil is made of 36 turns AWG 7/41 RF-litz wire. The turns are shielded to suppress eventually disturbing electric fields. The field pickup coil can be attached to RF-voltmeters with high impedance or to measuring equipment with 50 Ω input. Depending on the connected equipment the respective correction factors must be used.
