About Neodymium Magnets

Neodymium magnets, also known as NdFeB magnets or rare earth magnets, are considered the strongest magnets available today. 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. Custom boxes for premium products. Electric...

The magnet grade, or N rating, refers to the Maximum Energy Product of the material from which the magnet is made; it refers to the maximum strength the material can be magnetized to hold permanently. Generally speaking, neodymium magnets range from N35 to N55 in grade. The higher the grade, or N number, the incrementally stronger the magnet will be.   The grades of neodymium magnets that we normally carry are N42, N48 and N52, a rating that is generally measured in Tesla metrics or units of Gauss Oersted (MGOe). A magnet of grade N42 has a Maximum Energy Product of...

Developed by physicists during the 1970s, neodymium magnets are considered to be the strongest permanent magnets in existence. This is because they create the highest magnetic field per size and volume of any other known natural or manufactured material. The magnetic field typically produced by rare earth neodymium magnets can be in excess of 1.4 Teslas, whereas all other magnets normally generate fields of 0.5 to 1 Tesla. And not only are neodymium magnets the most powerful magnets on the planet, they are also the most affordable type of rare earth magnet available today.

Neodymium magnets are used in numerous applications requiring strong, compact permanent magnets. They are used in electric motors for cordless tools, in hard drives for most electronic devices and as attachment fasteners for doors, cabinets, blinds, retail displays, high-end product packaging, luggage, purses and jewelry clasps. Neodymium magnets are also used to make a tight seal on the doors to refrigerators and freezers. They power speakers in stereos, earphones, cell phones, computers, laptops and televisions. They are also used to store data in computers, and are important in scanning machines such as MRIs or magnetic resonance imaging machines. Originally, the high cost...
