Let's look at a simple application of Faraday's law. In (Figure 1), the magnetic field in the region between the poles of the electromagnet is uniform at any time but is increasing at the rate of 0.020 T/s. The area of the conducting loop in the field is 120 cm² , and the total circuit resistance, including the meter, is 5.0 N. Find the magnitudes of the induced emf and the induced current in the circuit.
