Quiz # 5 Physics 230 Prof. Hadley 1. Question: THE PROBLEM: You have a length of wire looped to form a circle of radius 25cm with its two ends attached to an external circuit. A constant magnetic field of B = 0.085T is perpendicular to the plane of the loop, but inward (in the direction opposite the normal to the loop). The loop is then increased to a radius of 45cm in a time of 0.75s. Answer the following questions : Question 1: What is the magnetic flux through the loop initially? Your Answer: -0.017 Tm 2 CORRECT -0.13 Tm 2 1.7 Tm 2 0.0167 Tm

    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.
