Worksheet 2.3

Name:__________________________________

Date:__________________________________

In the table below, record your observations for the 6 different configurations of your electrical circuit in Step 6 of Activity 2; for example, the short coil with 2 batteries in series. Be as qualitative as you like in the compass deflections. You could simply state that the closest compass (compass 1) deflected strongly, weakly, or not at all for a given configuration. Use a ruler, if you can, to measure the horizontal distance that the coil shoots.
