North/South Magnet Marbles (Red/Blue) Set of 400

Perfect for science and engineering exploration and investigations, each marble features a red north pole and a blue south pole.  Simply give them a roll to see opposite poles roll toward each other and attract... or make poles repel.  Add to the learning by incorporating a magnet wand or another magnet in a different format (not included).  Drag a string of marbles or make them spin, wiggle, or jump.  Safe, low power magnet marbles measure .63" D.

• Color coding that provides a clear and simple way to demonstrate attraction and repulsion!
• Hands-on, interactive manipulatives for teaching magnetic force, energy, and motion!
• Low-power, safety-tested magnet marbles that are approved for safe use for ages 4+
• Enough marbles for multiple small groups or science stations
• Red north and blue south poles give students a clear visual on magnetic attraction and repulsion.
• The round shape makes the magnets roll when pushed or pulled from the force of attraction or repulsion.
• Fun, first-hand experiences with cause and effect, magnetic forces, energy, and motion...in action!
