Hang on, I had that mixed up. It should be more like: (5x10^-5)/sin(58°) = B/sin(32°) Which would make B = 3.1x10^-5 T Much more reasonable.

So by using the law of signs, I would get: (5x10^-5)/sin(32°) = B/sin(58°) Solving for B I get 8x10^-5 Is this right? The magnitude of B seems high to me. Shouldn't it be smaller than the Earth's field?

1. You are standing directly under a high-voltage power line that is 4.5m above you, and a detailed map that you have indicates that the power line runs exactly north to south. Your compass needle makes an angle of 32 degrees to the east with respect to the power line's direction. a)Knowing...
