Imagine a substance in an electric field. You don't want the electric field to interact with the object you have put in its way. What should be the type of material this magnet should be made of to stop the effect of "magnetic shielding"?
Paramagnetic Diamagnetic or Ferromagnetic ?
My theory was paramagnetic, but I believe that isn't the answer since the field will pass straight through iy
Magnetic shielding materials re-direct a magnetic field so it lessens the field's influence on the item being shielded. Shielding does not eliminate or destroy magnetic fields, nothing does. It does, however, provide an easy path for the magnetic field to complete its path. You may think of it as a magnetic field conductor. This leads to what type of material can provide the best path for magnetic fields and thus create shielding. Since the field is attracted to the shielding material it stands to reason that if a magnet is attracted to the material (ferromagnetic material), that material can provide some amount of magnetic shielding.
