Where can I buy rare earth magnets is a question that may be on the minds of many consumers. Rare earth magnets are super-strong magnets. Advancements in recent technologies make neodymium magnets the most sought after permanent, commercial magnet material that is available today.

Though their name would lead you to believe otherwise, rare earth magnets are not rare at all. These “permanent” magnets are manufactured using metal alloys (made from rare earth elements) that are as common as iron and tin. The term “rare earth” was derived from scarce earth minerals, which are dispersed within the earth’s crust making their collection uneconomical. Unlike transition metals, the 17 rare earth elements are ferromagnetic and can be magnetized. It is the compound of these metals that creates the two types of rare earth magnets, which are superior in performance (up to 3 times stronger) than their conventional ceramic (ferrite) or alnico counterparts.

There is a type of flashlight that requires no batteries and it can always be recharged simply by shaking it. The process by which this works is surprisingly uncomplicated. Such a flashlight contains only a few basic components that, when aligned correctly, produce this amazing effect. Rare earth magnets, wire coils, capacitors, and light bulbs are all that is needed to construct the self-powering function of these flashlights.
