Helmholtz coils consist of two identical "thin coils, separated by a distance equal to the radius of the coil The two coils are connected in senes and further connected to a fluxmeter. Using this configuration one can measure the open circuit magnetisation of magnets of high coei-cive force such as Ferrtte, Rare earth. Cobalt and Nd-Fe-Bo magnets Measure­ments made with potential and Helmholtz coils allow us to consfruct the second quadrant magnetisation curve of these magnets.

Helmholtz coils are available in two sizes:

Hysteresis graph Model BH 8000 is a high precision system for plotting Hysteresis Curves on both hard and soft magnetic materials.

It is simple to operate and does not need any special skills or knowledge of electronics. It plots a BH curve in less than 20 seconds.

The measurement of induction (B ir B-H) is accomplished by means of a search coil which can be

• Wound around the sample itself
• Wound around a bobbin which encloses the sample
• Embedded into the poile pieces of the electromagnet

The search coil output is fed into the electronic indicator, which continuously integrates the singal and feeds it through the control panel to the Y axis if the XY recorder.

The Coercive Force (Hc) is measured by the Hall gauss meter. The Hall probe drives the gauss meter whose signal passes through the control panel to drive the X axiz of the XY recorder.

These reference magnets are made of AL-Ni-Co permanent magnets and are used to calibrate Hall effect gauss meters. They are stabilised during production to guard against irreversible losses resulting from temperature changes and external magnetic fields. They are suitable for transverse Hall Probes of dimensions 10 x 5 x 2 mm and are calibrated with primary standards . These magnets are available with the following flux densities.
