Helmholtz coils and fluxmeter

Helmholtz coil and IFM06 fluxmeter

Helmholtz coils for measuring the moment of permanent magnets are available and can be used with the Hirst IFM06 Integrating fluxmeter. These are simple to use devices where the user only needs to reset the fluxmeter, place the magnet in the center of the coil, place the fluxmeter in measure and remove the magnet to get a reading.

This can be used to provide a total magnetic moment for incoming magnetised magnets and if the magnet volume is known Br, HcB and BHMax parameters can be calculated.
