What is a super magnet?

"Super Magnet" is a generally slang term for non -dense magnets, the strongest permanent known magnets. It can also be a term for a powerful solenoid, such as the type used in FMRI hospitals (functional magnetic resonance imaging). Both magnets are much stronger than typical Ferrite Bar magnets and can be a health danger to those who wear pacemakers. Non -densemia magnets are also so strong that one can be injured by just playing with large samples - the power they create in unification can be strong enough to pierce human skin. The cost of non -omitory magnets is about $ 44 (US dollars) per kilogram ($ 97 USD per pound). Have become only widely available from the age of 90. Unlike ferrite magnets that are dull gray, the super magnet is not shiny and silver, like polished stainless steel. DYMIUM nestagnets can hold 1300 times higher than their own weight, strength ratio to weight similar to the ratio of the strongest animals such as tRopic mite archeetes Longisetosus . This means that the super magnet Nezhymium Neshymium can withstand an iron ball of 1.3 kg (2.8 lb).

Nemzymium magnets have a number of uses, the most common being for stabilizing and angular head motors in computers' hard drives. Magnets are also popular among fans who use them to build unique structures held by small magnets. Nemzymium magnets are also popular among natural science teachers who use them to demonstrate Lenz's law-Ev, which show magnetic magnetic magnetic when they bring almost conductive, non-ferrous metals. This can be shown that you drop the non -de -repair magnet with a copper pipe. The magnet falls remarkably slowly when it gets down the tube.

neonsmium magnets should be used carefully. If they swallow, they can write the lengths of the intestine, causing gastrointestinal perforation, which mayTo reopene death if surgery is not immediately performed. As already mentioned, non -densemia magnets are dangerous for people with pacemakers. In addition to health, neodymium magnets may be dangerous to data: These magnets are one of the few materials that can delete credit cards and spoil the hard disk data so intensely that they become irreparable, even with the best techniques. Large magnets NECHRYMIA tend to attract each other or iron objects so intensely that they break and send magnetic shrapnel shards everywhere. Large neodymium magnets should be processed carefully.
