Purpose: The purpose of this trial is to examine the capability of an electric current to produce a magnetic field. Apparatus: Items needed for this experiment are: 1. Coil (with 10 turns of wire) 2. Magnetic compass 3. Meter stick 4. Milliammeter 5. DC power supply 6. 10 Ohm resistor 7. Lab supports Method: In this experiment we connected a coil, 10 ohm resistor, and DC power supply. We set the compass to where it pointed at magnetic north. In part one, the current was set at 50, 100, 200, 300, and 400 for the distances of zero, the radius, and two times the radius away from the center of the coils. Then, it was reversed. All the data was recorded so that calculations could be made. Part two was done in about the same way except it was three runs set at 400 and then three runs done in reverse. All of this was also recorded and distances of zero, the radius, and two times the radius away from the center of the coils. This data was documented so that calculations could be made.
