Iron and cut a small gap into it, just big enough to fit whatever you want to expose to the field. Symbol. Types of Magnetic Materials. This is because of how speakers work. Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets, or are attracted to magnets. Like all types of steel, this alloy is highly impact resistant and scores mid-range on the Mohs scale. In fact, we can't make magnetic fields stronger than a million gauss or so without our machines just breaking down. However, applying a layer of water-based primer is a good idea when using the paint on new absorbent drywall. Even with the strongest diamagnetic materials, though, the force is very small. the field gets weaker. Our favorite magnetic strip, the Jonathan Alden, had the strongest field at 2352. An anonymous reader quotes a report from Motherboard: Earlier this year, researchers at the University of Tokyo accidentally created the strongest controllable magnetic field in history and blew the doors of their lab in the process. The formation mechanism of such strong fields outside umbrae is still puzzling. 19).
