Question

use the drop-down menus and your data table a from your student guide to complete the statements. make sure you use the values from the lightbulb in the original position. once the magnet moved closest to the loop in the forward direction, under normal magnet polarity, the approximate magnitude of the induced current shown on the galvanometer was ▼ ma. once the magnet moved closest to the loop in the reverse direction, under normal magnet polarity, the approximate magnitude of the induced current shown on the galvanometer was ▼ ma. once the magnet moved closest to the loop in the forward direction, under reversed magnet polarity, the approximate magnitude of the induced current shown on the galvanometer was ▼ ma.

Explanation:

To solve this, we rely on the experimental data from Data Table A (from the Student Guide) for the lightbulb in the original position. The induced current magnitudes depend on the magnet's motion direction (forward/reverse) and polarity (normal/reversed), following electromagnetic induction principles (Faraday's law, Lenz's law).

Step 1: Forward Direction, Normal Polarity

From the data table, when the magnet moves forward (toward the loop) with normal polarity, the induced current magnitude (e.g., typical values from such experiments might be around 20 mA, but this depends on the specific table). Assume the table gives a value like $\boldsymbol{20}$ mA (replace with actual table value).

Step 2: Reverse Direction, Normal Polarity

For reverse motion (magnet moving backward toward the loop) with normal polarity, the induced current magnitude (e.g., if the table shows 20 mA here too, or a different value—again, based on data). Suppose the table gives $\boldsymbol{20}$ mA (adjust to match data).

Step 3: Forward Direction, Reversed Polarity

With reversed magnet polarity and forward motion, the induced current magnitude (e.g., same magnitude as normal polarity forward, but direction reverses—magnitude remains, say, $\boldsymbol{20}$ mA, per data table).

(Note: Replace the values with the actual ones from Data Table A in the Student Guide. The above uses placeholders; the correct values come from the experimental data provided in the guide.)

For example, if the data table shows:

• Forward, normal: 20 mA
• Reverse, normal: 20 mA
• Forward, reversed: 20 mA

Then the answers would be 20, 20, 20 (adjust to match your table).
