It is sometimes used to bar radio frequency electro magnetic rays as well. This method is known as RF Shielding.
Depending on the material and its physical properties such as size, shape, thickness, and the frequency of electromagnetic fields and even the orientation of the material vis-à-vis magnetic field, the effects of magnetic shielding can be reduced or increased.
We must note that magnetic fields are only redirected using these materials and not created or destroyed. This is because magnetic field lines are attracted into the material and kept from spreading out as they take the path offering the least resistance (Appleman and Dailey, 1974). The reason for this stems from Maxwell’s equation.
Using one magnet, each of the three materials was brought closer to it. The idea was to see which ones are attracted and which ones are not. The former being classified as magnetic and the latter as non magnetic.
Firstly, one of the neodymium magnets was brought closer to the other which was attached to the thread. The magnet visibly moved towards the other magnet and thus it was established that a magnetic field exists. Then the only non-magnetic conductor here i.e. Aluminium was placed between the two and then the neodymium magnet was brought towards the other. It was interesting to note that although the magnet on the thread did not come comparatively closer to the aluminium, it does exhibited an interesting phenomenon. as the magnet on the other side of aluminium was moved, so did the magnet on the thread. This means that although aluminum is non-magnetic, it does interact with magnets in other ways.
Procedure and observations:The magnet was brought closer to the copper pipe. No force was experienced and both the magnet and copper offered no attraction. Thus, copper is deemed as non-magnetic. However, it cannot be used for magnetic shielding since the effects of magnet were seen on the other side of the copper as
