4 - Ampere and Faraday A loop of wire is place above a long straight wire which has a switch. The switch is suddenly closed and a current I flows through the wire toward the right. I 5w itc h 'O O 19. What is the direction of the B field (generated by the straight wire) in the center of the loop? 20. What is the direction of the induced B field in the center of the wire? 21. What is the direction of the induced current in the loop? 22. What is the direction of induced B field on the straight wire? 23. What is the direction of the magnetic force acting on the straight wire? 5 - Electric Generator Click Show in order to display the physical quantities. 24. What is the angle between the loop and the B field when the flux reaches its maximum values? (deg) 25. What is the value of the current when flux reaches its maximum values? (A) Compare the rotation period at 4.0 s and 2.0 s. 26. How are the maximum values of the fluxes different? 27. How are the maximum values of the induced current different
