  The uses of a Neodymium Magnet are endless, and they can be used to perform investigation and evaluate experimental designs. These magnets can exert forces on objects without making physical contact, and they provide evidence of fields between two objects. Using these magnets is useful in many fields.A standard describes the structure and properties of matter. It explains how pure substances are identified by their characteristic chemical and physical properties, and it explains the relationship between force and energy. A neodymium magnet is composed of a powder of neodymium and other elements. The neodymium magnet has a magnetic energy product B*Hmax of 18 times higher than that of an ordinary magnet. Another benefit of this rare-earth magnet is its size. A neodymium magnet can be as small as a quarter of an inch in diameter. Neodymium magnets are rare-earth elements, a rare-earth element. Despite being abundant in the Earth's crust, they are not commonly found in economic
