An electric field is directed out of the page within a circular region of radius R= 3.00cm. The magnitude of the electric field is given with E= (0.500 V/m*s)(1-r/R)t, where t is in seconds and r is the radial distance (r is less than or equal to R). What is the magnitude of the induced magnetic field at radial distances (a) 5.00 cm and (b) 2.00 cm?
