You have a circular wire loop of radius \(a=0.50 \mathrm{~m}\). It carries a current that increases linearly from 0 to \(4.5 \mathrm{~A}\) in \(0.30 \mathrm{~s}\). At the center of this loop is a wire loop of radius \(b=0.0020 \mathrm{~m}\) and resistance \(R=0.80 \mathrm{~V} / \mathrm{A}\). The loops are coplanar. What is the current induced in the smaller loop?
