the end of the experiment. The rated battery capacity is the total charge the battery can give up. Unfortunately, only about 85% of this charge is actually useable in our experiments. Therefore, you will need to multiply the rated battery capacity by 0.85 to find the useable charge in this experiment. As the battery gets weaker, the

Experiment 6
There are two 9-volt batteries already installed in the photodiode housing. To check the batteries, you can use a voltmeter to measure the voltage between the output ground terminal and each battery test terminal. The battery test points are located on the side panel. You should replace the batteries if the voltage is less than 6 volts.

How to Make a Homopolar Motor | STEM Activity
When the wire touches the top of the battery and the magnet (which is touching the bottom of the battery) at the same time, electrical current flows through the wire. This electrical current passes through the magnetic field created by the magnet. This results in a force that pushes on the wire, causing it to spin around the battery.
