These magnets are commonly used to identify the polarity of other magnets. As the north pole of these magnets are identified by a dimple it is easy to use the rule that like poles repel and opposite poles attract to determine the polarity of other magnets. Their size makes them easy to handle but so that they aren't so strong that they are difficult to remove from other magnets.
