Magnetic Measuring Instruments

Product Details:

These reference magnets are made of AL-Ni-Co permanent magnets and are used to calibrate Hall effect gauss meters. They are stabilized 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.

• For transverse Hall Probes : 1, 3, 5 Kilogauss nominal value
• For Axial Hall Probes : 1 Kilogauss

Accuracy:

• Within +5% of the nominal value. Individual magnet is designated with the actual flux density within + 1% at 25*C

Magnetic Stability:

• Magnets will not be permanently affected by stray fields below 150 Gauss

We are offering Self Field Coils to our clients.

Product Details:

Precision 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 sense and further connected to a flux meter. Using this configuration one can measure the open circuit magnetization of magnets of high force such as Ferrite, Rare earth. Cobalt and Nd-Fe-Bo magnets Measure­ments made with potential and Helmholtz coils allow us to construct the second quadrant magnetization curve of these magnets.
