These mini rectangles are very handy. They are great for hanging papers and posters and most anything else you can think of. This is a very handy and popular size of block magnet. The grade N52 version is considerably stronger than the standard grade N42 B842 block magnet. These blocks are useful for a wide range of magnetic applications.
Neodymium magnets are a member of the Rare Earth magnet family and are the most powerful permanent magnets in the world. They are also referred to as NdFeB magnets, or NIB, because they are composed mainly of Neodymium (Nd), Iron (Fe) and Boron (B). They are a relatively new invention and have only recently become affordable for everyday use.
