Minimize Effects of Earth's Magnetic Field

[RobertL]

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!

Homework Statement

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

(minimise the effect on what? )

physics is equations, so what is the equation here?
