Is there a substance that can block a magnetic field?
1) “Designing magnetic shielding is not a hard science, and sometimes only experience, careful attention to detail, and some trial and error testing are available to produce the desired outcome.” “Remember that magnetic shielding is not really “shielding” in the traditional sense. One cannot stop or block magnetic field lines. They will travel from the N pole of the source to the S pole. What we can do is to alter the path that these magnetic fields lines take on their journey. Magnetic shielding materials “conduct” magnetic field lines better than air (and most other materials). In a sense, they create a “path of least resistance” in which the magnetic field lines can travel. But the magnetic field lines will travel in this alternate path if it is a lower energy path.” Source: http://www.lessemf.com/guidelines.pdf 2) “The shielding materials we use for the mitigation of magnetic (low frequency) interference are the proprietary alloys NETICĀ® and CO-NETICĀ® which were developed by us spe
