There are various types of ways and materials used in Magnetic Shielding depending on the frequency and strengths of the magnetic field. MuMETAL®: A registered trade name for a high-permeability alloy used for magnetic shielding.
The field can, however, be redirected.
Most people are familiar with what a Magnetic Shield does, it simply stops or negates unwanted interference from magnetic fields. Its composition of 80% nickel, 4.5% molybdenum and balance iron gives it highly permeable properties. This is especially true if you are still using WiFi and have not gone-wired. It is made up of 80% nickel, 15% iron, and a balance of other metals depending upon the particular formula. This is achieved by using a metallic screen to absorb the electromagnetic interference that is being transmitted through the air. Not so many people are familiar with how it actually does it. How does EMC Shielding work? This tells us that the material has high magnetic susceptibility to an applied magnetic field; it readily accepts the flow of magnetic field.
In the series of pictures below, follow the lines of flux as paths from one pole of the magnet to the other.
Magnetic Flux Density: Describes the concentration of magnetic lines of force in a material.
However, you can still apply EMF shielding paint but you will need to plan carefully. The simple answer is yes.
The main purpose of effective EMC Shielding is to prevent electromagnetic interference (EMI) or radio frequency interference (RFI) from impacting sensitive electronics. Mu Metal® is the most widely used alloy for magnetic shielding purposes.
First, one important point must be clear: Magnetic shielding does not block a magnetic field. When you apply this paint to your house, you will also be affecting the signals generated by devices in your house. No material can stop the lines of flux from traveling from a magnet's orth pole to it's south pole.
