This magnetic field generating coil is used in Magnetic Susceptibility Tests for qualifying equipment to specification MIL-STD-461D & 462D. method RS01. It is built in rigorous conformance with the description in that specification and is made of Delrin. When RS01 is being performed, a 1Ω, 100W resistor should be connected in series to monitor current by a suitable meter. (item 267B). However, some aspects of Mil.Std. 462D require a monitoring loop to actually confirm the strength of the magnetic field at a specific point. This monitoring loop can be found under (item 317). See inset photo.
