Assume that (i=10 e^{-0.1 t} mathrm{~A}(t) in seconds). Calculate the flux (Phi(t)), at time (t), of (mathbf{B})

Question:

Assume that $i=10 e^{-0.1 t} \mathrm{~A}(t$ in seconds). Calculate the flux $\Phi(t)$, at time $t$, of $\mathbf{B}$ through the isosceles triangle of base $12 \mathrm{~cm}$ and height $6 \mathrm{~cm}$ whose bottom edge is $3 \mathrm{~cm}$ from the wire, as in Figure 17. Assume the triangle is oriented with normal vector pointing out of the page. Use Faraday's Law to determine the voltage drop around the triangular loop (the boundary of the triangle) at time $t$.
