3. Electromagnetic Inductance. Consider a single loop under magnetic field. (a) If the area A = 0.012[m) is constant, but the magnetic field is increasing at the rate of 0.020 T/s), determine the induced emf. (Use Faraday's law; the induced emf in a loop equals the absolute value of the time rate of change of the magnetic flux through the loop.) (b) If the total resistance of the circuit is 5.0(82), find the induced current. (c) Suppose we change the...

A conducting square loop is in a uniform magnetic field B as shown. The side length of the loop is L = 60 cm, and the loop has an effective resistance of R = 0.045 Ohm. The magnitude of B decreases steadily from an initial value B_0 = 0.050 T to zero in 0.20 seconds, and stays at zero afterwards. Find the magnitude of the induced emf in the loop. What is the current in the loop? And in what...
