This arc neodymium magnet is made of a top quality NdFeB magnetic alloy under the ISO 9002 quality systems. The magnet is magnetized through the thickness with north pole on the inner diameter. It is coated with Ni+Cu+Ni triple layers. 15 pieces of this arcs can form a circle with OD=3.75", ID=3.372" and height=0.8". Neodymium magnets are very powerful for their size and can hold up to hundred times their own weight. A neodymium magnet on average is about 7 times as strong as a ceramic magnet of the same size. These magnets have a wide variety of applications ranging from the home to the workshop to the classroom.
