Poles are on the flat face sides. Magnetized axially through the thickness.
Grade N52, the strongest grade available
Zinc plated for rust and corrosion protection
Details: Neodymium rare earth magnets are stronger than the strongest ceramic magnets. Neodymium is highly resistant to demagnetization and will not lose its magnetization around other magnets. Plated with Zinc for rust and corrosion protection. These magnets are "H" class rated, which makes them more resilient to high heat applications. They have a max working temperature of 100 Degrees Celsius versus the 80 Degrees Celsius max of most Neodymium Rare Earth magnets. With a grade of N52, each magnet has an approximate pull force of 22lbs and a max surface field of 3200 Gauss.
