Question: Calculate the direction of Earth's magnetic field.
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:
θ=7.33° East of North
Angle below horizontal:
θ=65.66° below horizontal
Is my attempt correct?
If I did the first question correctly, I need help with this question:
Compare the direction of the projection of this magnetic field vector on the horizontal
plane (the angle to the east (or west) of geographic north) with the direction of the
I honestly don't understand what they're asking here. Are they saying to compare 7.33° with the direction of the compass? How do I find the direction of the compass?
Also, one last question:
The magnetic field in anywhere between two helmholtz coils is uniform, right?
