Question

Select True or False for each of the following statements regarding magnetism, and the earth's magnetic field "B."

(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) 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 parallel to B.          
            (True/False) Like magnetic poles attract.          
            (True/False) The vector B acts only on charges at rest.          
            (True/False) The magnitude of earth's B is about 1 Tesla.
