Question

9. (a) The current in a long straight conducting wire is directed upward and is steadily increasing at a rate didt. Find the expression for the induced emf in the stationary conducting loop. What is the direction (cw or ccw) of the current induced in the loop? Ignore the thickness of the wire. (b) Given a 12.0 cm, b 36.0 cm, L 24.0 cm and didt- 9.60 A/s, what is the value of the induced emf? (c) If the resistance of the loop is 2.00 2, what is the current in the loop? Hint for Part (a): First write the expression for the magnetic field due to the wire as a function of x, the distance from the wire. Then integrate this over the area of the loop to find the flux in the loop. Next use the flux rule to find the induced emf dx
