1. The problem statement, all variables and given/known data Estimate the magnetic flux (due to the Earth's field) through your body (back to front) if you stand facing North. What will be the net change in flux if you turn and face South? 2. Relevant equations Gauss's Law and variants [tex]\oint E\bullet dA [/tex] 3. The attempt at a solution In the past, for simple problems we would always just basically do Qenclosed/Epsilon0. But to be honest, I don't know where to head in this case. This problem is suppose to be more conceptual than an actual answer, but I'm missing something apparently. If someone could point me in the right direction it would be greatly appreciated.
