A circuit is set up with wires directly connected to the terminals of a 12 V car battery through a high capacity knife switch. One of the wires is placed between the poles of a strong horseshoe magnet. The switch is then closed for a short time and the magnetic force on the wire is observed. The experiment is repeated with the magnetic field direction reversed. (It is important to immediately reopen the switch to prevent overheating.)
Equipment:
- Car battery (12 V)
- Horseshoe magnet
- Knife switch
- Connecting wires
