Mu metal vs ferrite sheet.
Mu metal is a nickel iron soft ferromagnetic alloy with very high permeability which is used for shielding sensitive electronic equipment against static or low frequency magnetic fields it has several compositions.
A ratio used to measure the effectiveness of a given shield.
Magnetic capabilities and mechanical properties of mu metal.
You should keep that in mind making your selection.
You want to see a weaker magnetic field on the far side of the metal.

Ferromagnetism is derived from the unpaired electron spins in only a few metal atoms these being iron cobalt nickel manganese and some rare earth elements.
The treatment of a metal alloy or other material by heating to a predetermined temperature holding for a certain time and then cooling to room temperature.

In this particular case steel is usually the better choice.
One such composition is approximately 77 nickel 16 iron 5 copper and 2 chromium or molybdenum.
For example let s say you place a sheet of metal right next to a neodymium magnet.
