Moving Wire Magnetometer – NanoVolt Amplifier NVM-01

TYPICAL APPLICATIONS

• Vibrating wire and rotation coil magnetometry
• Thermocouple thermometry

By using purpose shaped Coils the NVM-01 can enable the measurement of very small changes in magnetic flux in a region of interest, e.g.:

• The technique of measuring the magnetic moment of a magnet by rotating it in a Helmholtz Coil and monitoring the Coil voltage can be extended to very low magnetic moments.
• Low levels of magnetic content can be detected by moving material or items though an appropriately dimensioned measurement Coil. For “soft” magnetic materials the sensitivity can be enhanced by applying a dc bias magnetic field.
• Fluctuations in the magnetic field near magnetically sensitive equipment or instruments can be measured with “Pick-up Coils” at the equipment or arranged in the Lab walls. The output signals can be used to correct the measured parameter or to drive active field cancellation coils
• Geomagnetic magnetic field changes due to natural or induced changes can be measured with a Coil of dimensions and turns scaled to the anticipated rate of change in magnetic flux.
• Low levels of magnetic field fluctuation or noise in nominally dc magnetic fields can be measured independently of the magnitude of the dc field value.
