Description: This demonstration shows that a magnet on a pivot will move in response to another magnet close by.
A variation of this is to put both magnets on a pivot and observe that opposite poles attract.
- 2 Bar magnets
- 2 Pivots
- Electric Magnetizer
- Using the electric magnetizer, magnetize two bar magnets.
- Place one magnet on a pivot and bring the other one near it. Note that like poles repel and opposite poles attract.
- Place the other magnet on a pivot and bring them near each other. Note that they align themselves with opposite poles facing each other.
