For the region where the magnetic field is zero, we again calculate the circulation of the electric field around a circular loop of radius r>R: \[\begin{aligned} \oint \vec E \cdot d\vec l = \oint...For the region where the magnetic field is zero, we again calculate the circulation of the electric field around a circular loop of radius r>R: ∮→E⋅d→l=∮Edl=E∮dl=E(2πr) The flux of the magnetic field through that loop is however related to the area of the region with the magnetic field (of radius, R): ΦB=→B⋅→A=BA=B0(1−at)πR2 Again, applying Faraday’s Law…
