This is the question:
At a certain location in the Philippines, Earth’s magnetic field of 39 µT is horizontal and directed due north. Suppose the net field is zero exactly 8.0 cm above a long, straight, horizontal wire that carries a constant current. What are the magnitude and direction of the current?
I had no problem finding the magnitude of the current, but I'm struggling with visualizing the direction of the current. I didn't really understand what "horizontal and directed due to north" meant.
Is anyone able to illustrate what is going on with the magnetic field and how the wire is affecting the field?
Thanks
