Hwk 10 Chapter 20. www.webassign.net/web/Student/Assignment-Responses/submit?dep= 131 33971 EJ a Search In the gray region, the magnetic field points into the page, and its magnitude is B = 1.6 tesla (a) Which of the following diagrams correctly shows the charge distribution on the moving loop? What is the direction of the conventional current? (c) What is the conventional current in the loop? A. ) Which of the following are true? Check all that appl V Because a current flows in the loop, there is a magnetic force on the loop. The magnetic force only stretches the loop: the net magnetic force on the loop is zero. The magnetic force on the loop is in the same direction as the velocity of the loop. (e) What is the magnitude of the magnetic force on the loop? 05:30

Explanation / Answer

induced emf = B h v

     = 1.6 x 0.07 x 7 = 0.784 Volt

current = e/R = 0.784 / 0.1 = 7.84 A

-----------------------------------

Power provided by loop = e^2 / R = 0.784^2 / 0.1 = 6.15 W

This power comes from magnetic force on loop:

and power = F . v

6.15 = F (7)

F = 0.878 N
