The IFM06 Fluxmeter measures the total magnetic flux in a volume contained within a coil (such as Helmholtz coils) whereas a gaussmeter measures the total flux density at a point where the probe is located. The IFM06 can measure magnetic flux, magnetic flux density or magnetic field strength.
The IFM06 digitally integrating flux meter is the most accurate and stable Hirst fluxmeter so far (supplied fully calibrated). This 6th generation of fluxmeter technology incorporates Hirst propriety Zero Drift Technology (ZDT) providing the most stable flux readings available in this the latest generation Hirst instrument.

When to use an IFM06 fluxmeter
Examples of when to use the IFM06 integrating fluxmeter include:-
To determine total flux of a magnet using Helmholtz coils
Quality control of magnetised assemblies
With a pair of Helmholtz coils connected to the IFM06 Integrating Fluxmeter the sample to be tested is placed within the coils. Using this set up the IFM06 Integrating Fluxmeter can be used to determine the total magnetisation of the sample.
To check and control a magnetisation process
The IFM06 Fluxmeter can provide the feedback in closed loop control of Hirst Magnetiser systems for optimal yield in production line magnetisation of permanent magnet rotors, sensors, loudspeakers and many other applications. A search coil is embedded into a magnetising fixture (which holds the material / part to be magnetised). The magnet charger magnetises the sample the IFM06 Integrating Fluxmeter measures the sample’s total magnetisation and determines if the magnetisation has achieved the desired result and can display pass / fail. In addition, the IFM06 is able control the magnetiser to incrementally magnetise the part to ensure optimal yield in the process.
A custom sensing coil can be added to the Hirst IFM06 integrating fluxmeter this allows for a fast, accurate and a low-cost measuring technique to monitor the quality of permanent magnet assemblies prior to final assembly into the motor.
Sample batch testing can be used to verify specifications of the magnet assemblies prior to assembly.
