The strongest permanent magnets in the world are neodymium (Nd) magnets, they are made from magnetic material made from an alloy of neodymium, iron and boron to form the Nd2Fe14B structure. When a magnetic field gets stronger than about 500,000 Gauss, objects get ripped to pieces by the intense forces. Any material could be magnetized and any material gas his magnetic saturation behind which it is not possible to increase the magnetic field. Strong enough magnetic fields therefore destroy objects as we know them. They contain iron oxide and other metals in a ceramic composite. The electric current magnetizes the core material. The magnetic field of a bar magnet is strongest at either pole of the magnet. Neodynium Iron Boron Magnets. A low-temperature superconductor would need a volume 40 times. C) It is the process in which warm material gets even warmer and cool material gets even cooler. 5 22. You can demonstrate the science of magnets at home, by producing and testing the strength of a magnetic field. Permanent. But some substances are strongly magnetic, which means most of their electrons spin in the same direction. For a magnet to stick to a fridge door, several physical effects inside of it need to work together perfectly.
