A picture of a sheet of MU metal

Mu Metal

Magnetic shielding (Mumetal) protects electronic circuitry, electron beam in a cathode ray tube like VDT, TV, computer etc.and it separates the victims from magnetic interference (EMI). Usually, the sources of this interfernce are permanent magnets, transformers, motors, solenoids and cables. It is now available at affordable prices for home and office use. This mumetal alloy (80% nickel, 15% iron, 4.2% molybdenum) is easy to trim with scissors and shape by hand. Can be formed into magnetic barriers on VDTs, buried wiring, speaker and more. With snug fitting shapes, get as much as 70% attenuation of the magnetic field with one thickness. Use multiple layers for even greater reduction. The shield shape plays an important role in the reduction of the of the magnetic sources. Closed shapes are the most effective for magnetic shielding such as cylinders.

We recommend the use of an accurate gaussmeter made by Integrity Design to determine the proper shape and positioning of the shielding, and to confirm that the fields have been adequately reduced.

CAUTION: Foil has sharp edges, We suggest to wear a special gloves
