This is a huge block magnet - and VERY strong as with all the NdFeB magnets. Treat these with extreme caution due to their large size! North and South poles are located on the opposite 3 inch X 1.5 inch surfaces. These the magnets we use for our larger wind turbine projects, including the 17' diameter wind turbine that powers our shop. They are expensive due to their size, but we offer a deep discount starting at qty 12.
