WebA metal rod of resistance 2 0 Ω is fixed along a diameter of a conducting ring of radius 0. 1 m and lies on x-y plane. There is a magnetic field B = ( 5 0 T ) K ^ . The ring rotates with an angular velocity ω = 2 0 r a d s − 1 about its axis. WebThis calculation of motionally induced emf is not restricted to a rod moving on conducting rails. With as the starting point, it can be shown that holds for any change in flux caused by the motion of a conductor. We saw in Faraday’s Law that the emf induced by a time-varying magnetic field obeys this same relationship, which is Faraday’s law.
