Made from neodymium, iron, and boron, neodymium magnets are essentially a source of energy or power and are known for their long-lasting strength and durability. As a result, they are widely used in virtually every industry and application where a magnet is required or preferred. Here is a list of the most common places you’ll find neodymium magnets in use today: Arts, crafts, and jewelry. Audio speakers. Bicycle dynamos Burglary, fire, and earthquake sensors and alarms.
