The magnetic field of a cylindrical magnet that has a pole-face diameter of 3.3 cm can be varied sinusoidally between 29.6 T and 30.0 T at a frequency of 10 Hz. That is, as a function of time and in units of Tesla, such magnetic field is given by
B(t) = 29.8 + 0.2sin(2pi 10t)
At a radial distance of 2.0 cm, what is the amplitude of the electric field induced by the variation?
