Please help! Calculating the direction of Earth's magnetic field 1. The problem statement, all variables and given/known data Calculate the direction of Earth's magnetic field. 2. Relevant equations 3. The attempt at a solution 3 components of the magnetic field: Geographic South to North: 0.01670 mT Geographic West to East: 0.002147 mT Up to down (up is the sky, down is the ground): 0.03722 mT Calculating angle East of North: tanθ=0.002147/0.01670 θ=7.33° East of North Angle below horizontal: tanθ=0.03722/√(0.016702+0.0021472) θ=65.66° below horizontal Is my attempt correct?
