Additional Details

Question 3: "Rotate the armature slowly, holding it with the hand, and test its polarity as it moves. 3. Do the poles change and, if so, when?" JFK's answer: "They change as shown by compass needles attraction and repulsion when the armature has moved slightly past the magnetic line."
