B) For a bar magnet, the B-lines exit through the N pole and return through the S pole.
C) Like magnetic poles attract.
D) The magnitude of earth's B is about 1E-4 Tesla.
E) The earth's B-lines are parallel to the earth's surface at all points.
F) B does work on a charge only when the charge has a velocity component parallel to B.
G) B acts only on charges at rest.
