Question
Select True or False for each of the following statements regarding magnetism, and the earth's magnetic field "B." B does work on a charge only when the charge has a velocity component perpendicular to B. Like magnetic poles attract. For a bar magnet, the B - lines exit through the N pole and return through the S pole. The earth's B lines are parallel to the earth's surface at all points. The magnitude of earth's B is about 1E-4 Tesla. The vector B acts only on charges at rest. B does work on a charge only when the charge has a velocity component parallel to B.Explanation / Answer
B) For a bar magnet, the B-lines exit through the N pole and return through the S pole.
