What metals block magnetic fields? MuMetal® is the most widely used alloy for magnetic shielding purposes. Its composition of 80% nickel, 4.5% molybdenum and balance iron gives it highly permeable properties.
What causes residual magnetism? Residual Magnetism occurs when a magnet fails to turn completely off. The magnetic flux is a result of a circuit being created between the rare earth magnets inside and the steel body of the magnet. The level of Residual Magnetism depends on the Shunting Technology and the overall design of the magnet.
Can magnetic fields damage the brain? Prolonged exposure to low-level magnetic fields, similar to those emitted by such common household devices as blow dryers, electric blankets and razors, can damage brain cell DNA, according to researchers in the University of Washington’s Department of Bioengineering.
What cancels out a magnetic field? The simple answer is that it is not possible to totally ‘block’ a magnetic field. The essence of a magnet, as determined by nature, is that magnetic field lines must terminate on the opposite pole and, therefore, there is no way to stop them.
