I am having trouble figuring out this question:

Part 1: A long staight wire carries a current due East. This wire creates, at point #1, a magnetic field that is derected at 40 deg below due South. From point #1, the wire is located:

50 deg below due North

50 deg below due South

40 deg above due North

40 deg above due South

50 deg above due West

50 deg above due East

40 deg below due West

40 deg below due East

directly above

directly below

none of these choices

Part 2: Refer to the previous problem. An electron at point #1 is instantaneously traveling due North. Due only to the wire, the electron at #1 instantaneously accelerates:

East

West

North

South

directly up

directly down

50 deg N or West

50 deg S of East

none of the above
