Oersted's Experiment

This demonstration emphasizes the magnetic field produced by the motion of charged particles. A wire capable of carrying a high current is connected directly to a 12 V car battery through a high capacity knife switch. The switch is thrown closed for a short time and the effect of the current on a nearby compass needle is observed. (It is important to immediately reopen the switch to prevent overheating.) Equipment: Car battery (12 V) High current wire Knife switch Connecting wires Magnetic Compass ---------------------------- This video is part of the project "Videos of Physics Demonstrations", which is created by Dr. Galli and Dr. Amiri of Physics Department, Weber State University.
