Question
How would I go about part A to solve for B and C?
10. + A square loop of wire of side 2.3 cm and electrical resis- 2.3 cm tance 79 2 is near a 2.3 cm long straight wire that carries a cur- -9.0 cm- rent of 6.8 A in the direction indicated. The long wire and loop both lie in the plane of the page. The left side of the loop is 9.0 cm from the wire. (a) If the loop is at rest, what is the induced emf in the loop? What are the magnitude and direction of the induced current in the loop? What are the magnitude and direction of the magnetic force on the loop? (b) Repeat if the loop is moving to the right at a constant speed of 45 cm/s. (c) In (b), find the electric power dissipated in the loop and show that it is equal to al the rate at which an external force, pulling the loop to keep its speed constant, does work.
