Quizplus · Accepted Answer

The maximum value of the electric field is related to the maximum value of the magnetic field by the equation E = cB, where c is the speed of light. In this case, the maximum value of the magnetic field is 4.7 μT, so the maximum value of the electric field is E = cB = (3 × 10^8 m/s)(4.7 × 10^-6 T) = 1.4 × 10^3 V/m.
