The magnetic field $$B$$ at the conter of a circular col of wie camying a current 1 , as in (Fove .1), is Poughly estimate the current this locp would camy $$B=\frac{A\mathrm{NI}}{2r?1}$$ Express your answer to one significant figure and include the appropriate units. whice $$N$$ is the number of loops in the col and $$r$$ it its fadus. Imagine a simple model hi which the Enth's magnotic field of mbeat $$1\mathrm{G}(=1\times 10^{?4}$$ T) near the poles is produced by a single curent loop around the equitibe. incorrect, Try Againc 2 attempts remaining
