9. With the rod still inserted, place a current probe in the circuit between the power supply and
the variable resistor. The red connecting wire should be connected to the positive terminal
(red) of the power supply. Also connect a tap switch between the negative terminal (black)
of the power supply and the smaller solenoid. Open the Logger Pro file “Faraday's Law" in
the folder Lab 09 for current measurement and graph plotting, and zero the current probe.
With the tap switch closed, adjust the variable resistor to give a current of 150 mA. Observe
the maximum galvanometer deflection when the switch is opened and closed. Repeat with
currents of 175, 200, and 225 mA. Create a graph of galvanometer deflection vs. current.
