Abstract
Inductive magnetic field probes (also known as -dot probes and sometimes as probes or magnetic probes) are often employed to perform field measurements in electric propulsion applications where there are time-varying fields. Magnetic field probes provide the means to measure these magnetic fields and can even be used to measure the plasma current density indirectly through the application of Ampère’s law. Measurements of this type can yield either global information related to a thruster and its performance or detailed local data related to the specific physical processes occurring in the plasma. The available literature is condensed into an accessible set of rules, guidelines, and techniques to standardize the performance and presentation of future -dot probe measurements.
