If the shape is the same the permittivity and permeability of the material can play some role on how the magnetic field shape, and if the material is conductive (there are conductive plastics) there is a whole another class of possibilities. So when NIST tested how well concrete attenuated EMF radiation, they found the following: The attenuation is completely dependent on how thick the concrete is. Wood does not block, or shield, EMF radiation, but as you probably assume by now, wood does attenuate the radiation. Aluminum, the material that tin foil is made of, does conduct RF (Radio Frequency) and as a result, can block wireless EMF . 3. The magnetic force (or magnetism) can pass through thin sheets of non-magnetic objects such as paper, glass or wood. on what is in the market and found practically the same blocks that were a staggering two cents cheaper and had 125 magnetic blocks inside the package compared to HLAOLA which had 102 . Keep away from all devices and objects that may be damaged by strong magnetic fields, such as pacemakers. By measuring the magnetic field over the surfaces you could generate current loops to zero that field. Copper is used for radio frequency (RF) shielding because it absorbs radio and other electromagnetic waves. At frequencies from 30 to 100 MHz, aluminum foil provides at least 85 dB of shielding effectiveness. While it does block magnetism to some degree, it cannot completely stop any noncontact force. Does plastic block magnetic fields? Magnetic fields cannot be blocked, only redirected. Maybe something like that will cancel your nearby magnet and render the screen invisible to the magnet.
