The rectangle or block neodymium magnets are arranged by the length of the magnets. If you know the largest dimension of the rectangle you need, click the corresponding range below to narrow down the search.
The Block or Rectangle Neodymium Magnets includes all the NdFeB Rare Earth Magnets in the shapes of the rectangle, which include the cubes. But we also added a category for Cube Neodymium Magnets for those whose length, width and height are all equal. The order in which the rectangular neodymium magnets are arranged is by the length of the magnet, from small to large. So when you know the length you need for a magnet, you can click corresponding category to narrow down the search.
The smallest rectangle magnets we have in stock is 1/8” and the largest is 6”. In most cases, you can find a magnet suitable to your applications in stock but if it’s not the case, we can custom make for you. The largest rectangle neodymium magnets we can make is 8” in length and about 1” thick. And the thickest disc neodymium magnets we have ever made is 3”. Please fill the contact us form should you need a customized magnet.
There are three different directions to magnetize a rectangular neodymium magnet i.e. through length, width or the thickness. Most of our rectangular neodymium magnets are magnetized through the thickness with some through width or length. In order to make it clear, we lay the magnets so the north and south poles are always on the top or bottom surfaces in the product pictures. A pole indicator is also added in the picture for clarification. The part numbers are designed to show the polarity also. The same size magnets share the same part number but with S for magnetized through width and E for magnetized through length.
The rectangular neodymium magnets are also very popular shapes. They are used a lot in magnetic separation, magnetic retrieval, electrical motors, electrical generators, speaker and sensors. The magnet like 2x2x1”, 2x2x1/2” and 1x1x1/2” were used in magnetic separators since the early days when the neodymium magnet was invented. The 2x1x1/2” is used by Hugh Piggott in his Axial Wind Turbine design. The 4x1/2x1/4” is used as traffic light trigger, etc. To make the rectangle magnets easier to use, CMS Magnetics has developed the counter sunk (sink) hole magnets in different sizes.
