Pulsed Field Magnetometers

Hirst pulse field magnetometers are suitable for all types of hard magnetic material but they are especially useful for modern rare earth type materials such as NdFeB and SmCo magnets.

Hirst have produced Pulsed field magnetometers that can measure magnets as small as 1mm x 1mm x 1mm up to 70mm diameter x 50mm high and multiple sizes in between. Systems are available that can cool magnets to -40 degrees C or heat magnets to 220 degrees and then measure a full spectrum of magnet properties.
