Question

A compass is held 5.9 cm below a long wire that runs north-south. A current is switched on that causes the compass needle to point exactly northeast. The horizontal component of the Earth's magnetic field is around 2x10-5 T. (Hint: draw out the directions N, S, E, W as your coordinate axes before you draw your picture.) 1. Which direction does the current flow? a. North b. South c. Not enough info 2. What was the magnitude of the current through the wire?

          A compass is held 5.9 cm below a long wire that runs
north-south. A current is switched on that causes the compass
needle to point exactly northeast. The horizontal component of
the Earth's magnetic field is around 2x10-5 T.
(Hint: draw out the directions N, S, E, W as your coordinate
axes before you draw your picture.)
1. Which direction does the current flow?
a. North
b. South
c. Not enough info
2. What was the magnitude of the current through the
wire?
