Strong Magnetic Shielding by Common Available Material

Abstract

Purpose of this research paper is to find way to shield a very strong magnet that is of neodymium n50 grades or any other grade. There are several places where we require to shield the magnets completely or some sides/part of it. There are materials available in market for shielding but they are costly. The main aspect of this paper is to find a material by which we can shield very strong magnetic field and the cost can be reduced by significant amount. The method is to use many different common available material to shield it which are available commonly. The material that are being used are ferromagnetic, paramagnetic and diamagnetic. To find the perfect material for shielding we have to add different sheets of different material. The shielding also consists of some amount of rubber sheet. The final result of the experiment are we successfully finds a combination of material that shield the magnets perfectly in both attraction and repulsion. Magnet that are being used for the test have the power of 3900 gauss, they are made of NdFeB. The material that are available for shielding like Mu metal and more are costly and also can't shield very high magnetic field. The material which we have found can shield very high magnetic field but are not preferable where space is less. And the price of the ferromagnetic material is significantly low.
