Brand: Lake Shore | Category: Nanotechnology

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.

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.
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.
The Model 643 is a bipolar, 4-quadrant DC current source for driving laboratory electromagnets. It supplies up to +/-70 A at +/-35 V nominal, 2450 W, using fully linear regulation to keep current ripple low. The 4-quadrant output lets the field be swept through zero.
