PHYS 2426 Engineering Physics II Problem 30.10 1. The magnetic field in a region of space varies with time according to B = at3 + bt2 + c (2) where a = 3.00 T/s', b = 2.00 T/s2 and c = 0.500 T. The magnetic field is directed into the page and covers a circular area of radius r = 0.250m as shown in the figure. (a) Calculate the magnetic flux passing through a circular area of radius r = 0.150m at t = 2.0s (b) Calculate the emf induced around the circumference of this area at t = 2.0 s. (c) Calculate the electric field induced at a radial location r = 0.150m at t = 2.0s. (d) Repeat the above three steps and calculate the electric field at a radial location r = 0.350 m at t = 2.0s.
