Minimize Effects of Earth's Magnetic Field

Click For Summary
SUMMARY

To minimize the effects of Earth's magnetic field on a current-carrying coil, the coil must be oriented perpendicular to the direction of the magnetic field. In this discussion, it is established that the Earth's magnetic field is at an angle of 58 degrees from the horizontal, directed inward. Therefore, positioning the coil at a 90-degree angle relative to this field will effectively reduce its influence on the coil's operation.

PREREQUISITES
  • Understanding of electromagnetic theory
  • Knowledge of current-carrying coils

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? :confused:)

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