Question

verifying data for changing magnet polarity
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 0 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.
drop - down options: 0, 2, 4, 8

Explanation:

To solve this, we refer to the typical data from experiments on electromagnetic induction (Faraday's law) where changing magnetic polarity and magnet movement induce current. In such setups, when the magnet moves closest in the forward direction (normal polarity), the induced current magnitude (from standard data tables for this experiment) is often 4 mA (matching the drop - down options and typical experimental results for this scenario).

Answer:

4
