\f60:00 60 AND 830 UNIVERSAL INTERFA OUTPUTS O Figure 1 Experiment Apparatus Measurements to be done Measurement #1: emf (V) versus time (t). The emf is induced by dropping a magnet (with the N-pole downward) into the center of the solenoid. Measurement #2: Same as Data Set 1 but with the S-pole of the magnet downward. Measurement #3: emf (V) versus time (t). The emf is induced by dropping two magnets (in series as shown, and with the N-pole downward) into the center of the solenoid. SN S Measurement #4: Same as Data Set 3 but with the S-pole of the magnets downward. sm said to Attention: the initial position of the bottom of the magnets should be the same for all four measurements: 0.5 mm above the top center of the solenoid
