1) In this experiment, we will use two different field plates which are shown in Figure 2. We will start with the dipole (two-point) configuration. Figure 2: Parallel plate and dipole configurations 2) Turn the Field Mapping Apparatus upside down. Unscrew the two screws at the center. Place the dipole field plate with the conducting side facing away from the apparatus, as shown in Figure 3. Put the thumb screws back and tighten them to be snug against the plates.
