What Is Neodymium Magnets

Neodymium magnets are a combination of magnets made on the outside of neodymium, steel, and boron -- Nd2Fe14B. These magnets are very strong in comparison to their numerous counterparts, but are also mechanically fragile and lose their magnetism at temperatures above 80 degrees Celsius. Used for stabilizing and angular head motors in computer hard drives, Nd2Fe14B magnets are also common odditists, and a small magnet can have surprising properties -- it displays magnetic brakes when acting near a non-magnetic metal due to eddy currents, And A SOMEWHAT LARGER MAGNET STRONG ENOUGH TO GET ALONG WITH THE EARTH'S MAGNETIC FIELD ALLOWS ITS TENDENCY TO ASSOCIATE DIRECTLY WITH THAT FIELD WHEN IT IS HELD, WHICH IS ESSENTIALLY a COMPASS. Also, MAGNETS LESS THAN A CUBIC INCH IN SIZE CAN BE EXTREMELY LARGE TO DELETE THE DISK IN A WAY THAT INFORMATION IS IMPOSSIBLE TO RECOVER, ENSURING THAT NO CURRENT TECHNIQUES SUCH AS FORMATTING THE DISK ARE AVAILABLE. NdFeB magnets are often strong enough to not only magnetize color CRT shadow masks, but also twist bend masks. Such damage is typically irrepairable
