Set up instructions for 2-square loops of wire:

The 45 cm rod is inserted into the "A" base and tightened down. The pendulum clamp is tightened to the rod roughly near the top. The two lead wires for the small loop are placed under either side of the small metal plate of the pendulum clamp's far end screw. About 2 inches of the lead wires should be above the clamp. The lead wires for the large loop should be placed under the metal plates of the pendulum clamp's second and third screws. About 2 inches of the lead wires should be above the clamp. The pendulum clamp can then be slide up or down on the rod to match the position of the magnet. The students will make the final adjustments as needed during the lab time. There is no need to set up the variable magnet up in advance of the class. The only need to be set out on the table.

E/M apparatus setup instructions:

Set out one e/m apparatus on the TA's tables and one on a set up cart. The high voltage power supply is the only one that is needed. The 500 volt terminals of the power supply are connected to the acceleration plates of the electron gun. The 7 VAC terminals of the power supply are connected to the heater of the electron gun.
