No links pls: 26. What do you mean by electromagnetic induction ? State Faraday's law of electromagnetic induction. Figure shows a rectangular conducting loop PQRS in which the arm PQ is free to move. A uniform magnetic field acts in the direction perpendicular to the plan on the loop. Arm PQ is moved with velocity V towards the arm Rs. Assuming that the arms QR, RS and PS have negligible resistance and moving arm PQ has resistance r, obtain the expression for . a) The current in the loop b) the force required to move the arms PQ. c) the power required to move the arm PQ d ) the direction of induced current in the loop PQRS.
