Question

Increase and decrease the strength of the bar magnet (use slider) and continue to slowly move the
compass around the bar magnet. What effect does changing the magnet’s field strength appear to have
on the compass

Answer 1

Explanation:

Consider again the fact that the pole of a magnet that orients northward is called the north pole of the magnet. If unlike poles attract, then the magnetic pole of Earth that is close to the geographic North Pole must be a magnetic south pole! Likewise, the magnetic pole of Earth that is close to the geographic South Pole must be a magnetic north pole. This situation is depicted in Figure 20.5, in which Earth is represented as containing a giant internal bar magnet with its magnetic south pole at the geographic North Pole and vice versa. If we were to somehow suspend a giant bar magnet in space near

Answer 2

Answer:

Increasing the strength of the magnet makes the compass deflect more; decreasing the strength of the magnet makes the compass deflect less.
