Good sized block magnet of useful dimensions - and VERY strong as with all the NdFeB magnets. North and South poles are located on the opposite 2 inch X 1 inch surfaces.
This is the magnet set called for in both Hugh Piggotts Axial Flux Windmill Plans and the Otherpower.com Home-Brewed Wind Turbine design. Glue and casting resin stick to the epoxy coating better than to nickel plate, so we recommend this magnet for building wind turbine alternators.
Your magnet set will arrive packed in a steel-lined box, with separators between each magnet. Use caution while unpacking the box!
