Question

The square coil has sides l = 0.25 m long and is tightly wound with N = 200 turns of wire. The resistance of the coil is R = 5.0 Î©. The coil is placed in a uniform B field that is directed perpendicular to the face of the coil and whose magnitude is decreasing at a rate dB/dt = -0.040 T/s. (a) What is the magnitude of the emf induced in the coil? (b) What is the magnitude of the induced current?

Step 1

The formula for Faraday's law is given by: \[ \text{emf} = -N \frac{d\Phi_B}{dt} \] where: - \(\text{emf}\) is the induced electromotive force in volts (V), - \(N\) is the number of turns in the coil, - \(\frac{d\Phi_B}{dt}\) is the rate of change of magnetic flux Show more…
