For a bar magnet, the B - lines exit through the N pole and returnthrough the S pole .
2. The magnitude of earth's B is about 1 Tesla.
3. B does work on a charge only when the charge has a velocitycomponent parallel to B.
4. The vector B acts only on charges at rest.
5. B does work on a charge only when the charge has a velocitycomponent perpendicular to B.
6. Like magnetic poles attract.
