In Figure P29.40, \(R=0.12 \mathrm{~m}\) and a changing magnetic field creates an electric field that has magnitude \(E=10 \mathrm{~V} / \mathrm{m}\) at a radial distance \(r=0.060 \mathrm{~m}\) from the center of the magnetic field. What is the instantaneous magnitude of the time rate of change of the magnetic field?
