Answer to Question 1

2

Answer to Question 2

Near Earth's north geographic pole is a south magnetic pole. A compass needle
aligns its long axis with Earth's magnetic field. The north-seeking pole is called the
north pole of the magnet. Because unlike poles attract, the magnetic pole near Earth's
geographic pole therefore must be a south magnetic pole.
