NMR calibration of other mappers
For magnets with complex fields, such as quadrupoles and wigglers, the measurements are performed using a variety of other techniques: Hall devices, rotating coils, moving coils, moving wires, vibrating wires, pulsed wires, etc. All these techniques have one thing in common: they all need to be calibrated in a reference magnetA magnet used for calibrating a magnetometer.
