This arc neodymium magnet is made of top quality NdFeB magnetic alloy containing the elements neodymium, iron, and boron. All of our magnets are made under the ISO 9001 quality control systems. The magnet is magnetized through the thickness with south pole on the inner diameter. It is coated with Ni+Cu+Ni triple layers for a shiny finish and protection against corrosion. 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 many times its own weight.
- Magnetized Direction: through thickness. The south pole is on the inner of the circle.
