All magnets are not created equal. Neodymium magnets are a permanent type of rare Earth magnet, made from neodymium, iron, boron, and other transition elements. These are the strongest permanent magnets on the market today. Neodymium magnets have many uses, from a variety of industrial applications to an unlimited number of personal projects. They can be used in the manufacturing of motors, alternators, and actuators and are also great for crafts, school experiments, and DIY jobs. Use these for practically any light-, medium-, or heavy-duty project where super strong pull force is required.
