Measurement of a time-periodic magnetic field by rotating coil

TL;DR

This paper introduces a new data processing technique enabling the rotating coil method to measure dynamic, time-periodic magnetic fields in a single measurement during one cycle, capturing time-dependent multipoles.

Contribution

A novel data processing method that extends the rotating coil technique to measure time-varying magnetic fields within a single cycle.

Findings

Allows measurement during one power cycle or rotation period

Enables capturing time-dependent multipoles

Simplifies dynamic magnetic field measurement

Abstract

A novel technique of the measurement data processing is developed which allows to apply the rotating coil method for measurement of a dynamic magnetic field, periodic in time. The developed technique allows to obtain time-dependent multipoles in a single measurement which takes place during one power cycle of the magnet or the coil rotation period, whichever is longer.
