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