### What is magnetic screening? How do I protect a magnet ...

Not sure why you would want to ‘protect’ a magnet with screening but if you want to stop it’s magnetic field from affecting other things then you need to enclose the magnet in a material with very high magnetic permeability like ‘mumetal’. Steel w...

### Electromagnetic shielding - Wikipedia

Typical materials used for electromagnetic shielding include sheet metal, metal screen, and metal foam. Common sheet metals for shielding include copper, brass, nickel, silver, steel, and tin. Shielding effectiveness, that is how well a shield reflects or absorbs/suppresses electromagnetic radiation, is affected by the physical properties of the metal. These may include conductivity, solderability, permeability, thickness, and weight. A metal's properties are an important consideration in material sele

### What is Magnetic Shielding? (with pictures)

Jan 31, 2021 · J. Dellaporta Date: January 31, 2021 Magnetic field lines must always connect to a north magnetic pole and a south pole - field lines cannot be stopped, only redirected around sensitive objects.. Magnetic shielding is a process that limits the coupling of a magnetic field between two locations. This can be done with a number of materials, including sheet metal, metal mesh, ionized gas, or plasma.
