SOLVED: Cylindrical region with a radius of cm contains a uniform magnetic field parallel to its axis. If the electric field induced at a point RVv2 from the cylinder axis is 890.2 10^-3 V/m, the magnitude of the magnetic field (TIs) must be changing at the rate of 445. None of these options are correct: 6.68, 13.35, 11.13.
