These Helmholtz coils work with the Model 480 fluxmeter to measure the magnetic moment of permanent magnets and magnet assemblies. The sample sits at the centre of the coil pair and the flux change is integrated by the fluxmeter. Single and 2-axis configurations are available.

Lake Shore search coils are handheld coils used with the Model 480 fluxmeter to measure magnetic flux and flux density. They are optimised for magnets fixed in an assembly or mounted in a narrow gap, where a Helmholtz coil cannot be used. Two area-turn options are offered.
These Helmholtz coils generate a known, uniform magnetic field from an applied current, so they can be used to calibrate and check magnetic field sensors. Single-axis coils are offered in 2.5 in, 6 in and 12 in inside diameters, along with a 2-axis model. Field accuracy is 0.75%.
The EM-4V and EM-7V are laboratory electromagnets with indexed ExactGAP air gap settings and interchangeable pole caps. With the optional high-field 2 in pole face at a 7.5 mm gap they reach 2.76 T and 3.22 T. Field falls as the air gap or the pole face diameter increases.
