WebEarth acts as a giant magnet with magnetic poles and a magnetic field over which it exerts magnetic force. Earth has north and south magnetic poles like a bar magnet. Earth’s magnetic poles are not the same as the geographic poles. Earth’s magnetic field is called the magnetosphere. What gems are magnetic? WebA) The net force on a compass needle is zero because its north and south poles are pulled in opposite directions with equal forces in the Earth's magnetic field. B) When the needle is not aligned with the magnetic field of the Earth, then a pair of torques (relative to the center of the compass) is produced This pair of equal torques, called a ...
