If your permanent magnet application requires you to fasten your magnets securely to the wall (or any surface) this is the magnet for you. This powerful super magnet has a hole that is perpendicular to the poles. This means that when the magnet is fastened to a surface, the poles (strongest points of a permanent magnet) will be on the sides where the hole is.
