Suppose that in a system the following equation applies,                                        Bx=BmCos(t) Create a diagram of the system and define A, B, and .Use Faraday's Law to find the emf (t) induced in thecoil. Also, show that the amplitude of the induced emf is givenby                                           m=NSBmCos Suppose that in a system the following equation applies,                                        Bx=BmCos(t) Create a diagram of the system and define A, B, and .Use Faraday's Law to find the emf (t) induced in thecoil.

Explanation / Answer

B x = B m cos ( w t ) induced emf E = -N d / dt                       = -N d ( B x S ) / dt                      = -NS d ( B m cos ( w t ) ) / dt                     = -NS w B m [ -sin ( wt ) ]                    = NS w B m sin ( wt )                    = NS w B m sin          Since angle = angular velocity w * time t
