Unformatted text preview: Quiz 5: Ch 19-20 FORM C Problem 1 In the diagram the current in the long, straight wire is 11=5.00 A and the wire lies in the plane of the rectangular loop which carries a current of 10.0 A. The dimensions shown are c=0. 100 m, a=0. 150m and l=0.450 111. Find the magnitude and direction of the net force exerted by the magnetic field due to the straight wire on the loop. a) Fm=5.40x10'5 N to the right F__=l.35x10‘5 N to the left -_. - n,¢=l.35x10' N to the n Problem 2 What current is required in the windings of a long solenoid that has 1000 turns uniformly distributed over a length of 0.400 m in order to produce a magnetic field of magnitude 1.00x104‘T at the center of the solenoid? \ d) 1= l.40A e) I = 0.20 A Problem 3 A wire loop of radius 0.30 m lies so that an external magnetic field of magnitude 0.30 T is perpendicular to the loop. The field reverses its direction and its magnitude changes to 0.20 T in 1.5 5. Find the magnitude of the average induced emf in the loop during this time. a) e=l9mV b) a=38mV ci i=57mV e) e=6m' I ...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
