Example 22-2 An Electric Field Due to a Changing Magnetic Field
... From Equation 20-1, the initial magnetic flux is B = AB cos 0 = (9.62 * 1024 m2)(1.50 T)(1) = 1.44 * 1023 T · m2 The final magnetic field is zero, so the final magnetic flux is zero as well. The change in magnetic flux is B = (final flux) 2 (initial flux) = 0 2 ...
