These Neodymium  Magnets are magnetized through the 1" length meaning the poles are on the 3/8" x 3/8" ends. While they are powerful and can pinch, they are a great size for a bulletin board or your fridge, as just one of them will hold a stack of papers firmly in place, and they are large enough to grab and easily move.
