Neodymium Bar Magnets is one of the most popular brands on the market today. They are extremely strong and can hold up to 400 Gauss units. This is a very large amount for the magnetic properties of these items are such that they need to be placed in direct alignment with each other in order to have the desired strength. Once the alignment is achieved, the Neodymium’s magnetism will dominate.
The strongest Neodymium Bar or Block magnets (also shown on this page) usually come in several sizes. Neodymium Bar Magnets range from just under a quarter of an inch to well over two inches in diameter. They are great for working with any materials that are heavy enough to be magnets, including stainless steel, aluminum and even certain types of wood like cedar and spruce. If you have a smaller working area like a workshop then you may want to stick with the smaller bar magnets. However, they can be used for just about anything that needs to be magnetized, including paper clips and magnets that attach to screws.
The most common use for a neodymium bar magnet is in applications where one has to hold something very close to the surface. These magnetic items make it very easy for one to grip a thin metal object without damaging it. Another common application of these magnetic items is for holding fishing line to the reel of your reel.
