The figure shows a circular region of radius R =  m in which a uniform electric flux is directed out of the plane of the page. The total electric flux through the region is given by ΦE = ( V·m) sin(( rad/s) t), where t is in seconds. Find the maximum value of the induced magnetic field in 10-16 T that occurs at r = m.
