Magnetic Jewelry Clasp

There are two general types of rare earth magnets. These are neodymium magnets and samarium cobalt magnets. Neodymium rare earth magnets are an alloy comprising neodymium, iron and boron. These magnets are used in computers, car motors, speakers, headphones, cordless power tools and even children's toys. They have a stronger magnetism than samarium cobalt magnets and can be purchased at a reasonable price. However, neodymium rare earth magnets are also very vulnerable to corrosion. For this reason, all of these magnets come coated with a copper, nickel or gold covering.

Samarium cobalt magnets consist of cobalt, samarium and iron. These magnets are not as powerful as neodymium rare earth magnets but they are more resistant to demagnetization and are more stable under high temperatures. Samarium cobalt magnets are also resistant to oxidization, so they do not have to be coated. These magnets are generally used in traveling wave tubes and satellite dishes.

A person who purchases either neodymium magnets or samarium cobalt magnets should be well aware of the dangers that these magnets can pose. All rare earth magnets are extremely powerful and should be kept out of reach of children at all times. Those with pacemakers should not come near rare earth magnets, as these can negatively affect the pacemaker. Rare earth magnets should never be placed near a cell phone, credit card, computer, hard disk, thumb drive or other electronic device. These magnets have been known to erase electronic data and cause computer malfunctions. Neodymium and samarium cobalt magnets should be stored carefully when not in use.

A person can purchase pretty much any type of rare earth magnet via the internet. These magnets are sold in many shapes and sizes. In fact, one can even order a custom shaped magnet from some internet retail sites. A person who is buying rare earth magnets online will want to do some comparison shopping. Shopping comparison sites can help one to find the rare earth magnet that he or she needs at the best possible price.

Neodymium rare earth magnets and samarium cobalt magnets are fascinating. Without these magnets, humanity would miss out on a number of modern inventions. Neodymium and samarium cobalt magnets can be purchased online from a number of online retail sites. One can either purchase an already cut magnet or place a custom order for a particular size and cut of rare earth magnet.

However, it is important to remember that samarium cobalt and neodymium magnets are powerful and should be handled with care. One should never take the power of rare earth magnets for granted; the consequences of doing so can be dire. Rare earth magnets should be carefully stored out of reach of children when not in use. These magnets should also be kept far from any electronic storage devices.
