A variety of magnet tricks were on display as part of Physics Week at Bishop’s
During Physics Week, we had the chance to play around with various magnetic tricks. The one that captivated me was the balancing coins. We suspended a tower of coins underneath a strong magnet, the coins became magnetized and stuck to each other, and the magnet kept the column still, even against the force of gravity. Another display was the homopolar train. Magnets are placed at either end of a battery and pushed into a long copper coil. The magnets connect with the copper coils creating a circuit. The coils become magnetised pushing and pulling the battery through the long length of coil! All displays were a great visual way of showing how important physics and magnets are in technology and our every day lives. A fascinating set of activities for Physics Week!
