Find the magnitude and direction of the force on the slide wire (due to the magnetic field acting on the induced current in the wire). Ans: B A. 31.6 N В. 22.5 N С. 17.2 N D. 5.23 N 26. What if the slide wire was no longer be tugged at a steady pace but was, instead, being pulled according to the formula x = sin(7 ·t), where x represents the slide bar's position away from its starting point.(this means that someone is tugging it back and forth). What would be the magnitude of the induced emf at t= 1.75 second? (HINT: make sure your calculator is in radian mode). Ans: B a.0V b. 6.67V с. 10.7V d. 16.9V

The magnitude of the field strength is a constant 3.00 T in the direction shown in the figure (into the page). B-Field INTO the Page 19. Find the one term of the following that does NOT belong in the Faraday's law expansion for the induced Emf, Ans: D dB А. NA cos 0 dt do C. NBA sin O dt dA В. NB cos0 D. IL ® B dt 20. Which one of the following will be used to determine the induced Emf in this situation: Ans: B dB dA de NBA sin 0 dt а. NA -cos 0 b. NB- cos e d. IL ® B dt dt 21. Recognizing that L is constant and that the variable width of the loop is given as “x" (so that the area of the loop is A=xL) and that N=1, use the correct term from #17 to find the dx -mean?) Ans: A dt expression for the Emf induced in the loop (HINT: What does a. anf = BLv b. amf = H,ni c. amf = Be" |d. emf = (1-e") R 22. Find the magnitude of the induced emf. Ans: B A. 42V В. 15V C. 9V D. 23V 23. Find the magnitude of the induced current (HINT: Once you have the induced Emf, use Ohm's law). Ans: A A. 7.5A В. 18A С. 31А D. 2A
