North/South Magnet Marbles - Set of 100

Perfect for force, energy, motion 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 are approved for safe use for ages 4+. Each marble measures .63" D.

Includes 100 magnetic marbles in a jar.
