Suppose that After 15s, the normal to the coil is 60 with the magnetic field. The number of coil turns (n) is 100. Data: N = 100, R = 8 10 2 m, I = 0.4 A, . What is the instantaneous emf in the . What is the magnitude of the emf induced along the length of the moving bar? The magnitude of the magnetic field in the coil is 21.65 T. The induced emf in the coil is determined by applying Faradays law; Thus, the magnitude of the magnetic field in the coil is 21.65 T.
