Magnetic Shields

Open-end Magnetic Shield 100mmOpen-end Magnetic Shield 100mmCapped-end Magnetic Shield 100mm

These Mumetal cylindrical shields distort the magnetic field around their layers, shielding contents from external magnetic fields.

Both open- and capped-end versions of the shields are available with the capped-end available in two internal diameters. They also have additional shielding at either end of the sample chamber and are therefore less reliant on orientation. The open-end version of the shield will be most efficient when the axis of the shield is aligned in a magnetic East-West direction.

Either will typically attenuate the Earth’s field of ~50,000nT to a level of ~1nT, enabling the user to measure remanent magnetism in small components or errors in magnetic sensors.

In the event of mechanical shock and/or exposure to strong fields, low-level magnetism may accumulate inside the cylinder. This can be removed with the Degaussing Wand, ensuring that the field inside the cylinder is as close as possible to zero before critical measurements are made.

Typical applications:

• Calibration of magnetic field sensors.

• Measurement of remanent magnetisation.

• Storage of paleomagnetic samples.
