Question about magnetic fields in coiled conductors

  1. Jun 20, 2006 #1
    Okay, say I have a coiled conductor below where the direction of the magnetic field is indicated in the North direction.

    +()()()()()- ---> N

    If I were to place a compass in the following position, what would happen?

    (a)

    COMPASS +()()()()()-

    (b)

    +()()()()()- COMPASS

    Okay, so given that the north end of a compass is repelled by the north pole of any magnet creating the field, are my answers correct:

    (a) COMPASS needle will point ---> as it is attracted by the southern magnetic flow created by the coiled conductor.

    (b) COMPASS needle will point ---> as it is repelled by the northern magnetic flow created by the coiled conductor.

    Correct.

    Still, the better way to think about direction of compasses: a compass will allign itself with the net magnetic field it is in (with the north end pointing in the direction of magnetic flux).
