A group in class suggests a model of magnetism in which an unrubbed iron nail contains many N and S entities randomly arranged. When a magnet is rubbed from one end of the nail to the other, their model says that the entities re-distribute themselves according to the following diagram: Fig. 1: S SS S SSNN NN N N S SSS S SN N NNNN Consider the following three observations that could be made with a magnet-rubbed nail: 1. When one end of a magnetized nail is brought near the rubbed nail, it attracts one end of the nail and repels the other end. 2. When the rubbed nail is cut in three equal pieces, each of the three pieces still behaves like the uncut rubbed nail. 3. When one end of the rubbed nail is brought near the East label on a compass, the compass needle rotates. [Assume before the rubbed nail was brought near, the compass needle pointed north.] Which of the above three observations would this model be able to help explain? O Observation 2 only O Observation 1 only Observations 1 and 3 Observations 1 and 2 O All three observations
