Homework Help: Minimize Effects of Earth's Magnetic Field

  1. Oct 18, 2012 #1
    Hey,

    So if I were doing an experiment in which I have a current carrying coil, at what angle to the earth's magnetic field would I need to rotate the coil in order to minimize the effect of earth's field? I was assuming parallel to the direction of the earth's magnetic field. I assume it has to be perpendicular, parallel, or antiparallel. Any ideas? Thanks!

    1. The problem statement, all variables and given/known data

    In this case, the earth's magnetic field is 58 degrees from the horizontal pointed inward.

    2. Relevant equations

    Unknown

    3. The attempt at a solution

    See above

    Hey RobertL! Welcome to PF! :smile:
    (minimise the effect on what? :confused:)

    physics is equations, so what is the equation here? :smile:
