This work investigates an innovative magnetic field probe especially suitable but not limited to the characterization of insertion devices for light sources such as undulators and wigglers. Examples of such systems include the undulators planned for the Advanced Light Source Upgrade (ALS-U), where a complete magnetic characterization of the device is an integral part of their construction and certification. Current magnetic field measurement technologies for such hardware include Hall effect probes, wire-based systems, and sensing coils.
