Question

A conducting loop is made in the form of two squares of sides s1- 3.9cm and s2 6.7 cm as shown. At time t-0, the loop enters a region of length L = 19.5 cm that contains a uniform magnetic field B-1.8 T, directed in the positive z-direction. The loop continues through the region with constant speed v = 44 cm/s. The resistance of the loop is R 1.4 2 1) At time t = t1 = 0.03 s, what is l 1, the induced current in the loop? 11 is defined to be positive if it is in the counterclockwise direction. A Submit 2) At time t- t2 - 0.583 s, what is l2, the induced current in the loop? l2 is defined to be positive if it is in the counterclockwise direction A Submit 3) what is Fx(Q), the x-component of the force that must be applied to the loop to maintain its constant velocity v = 44 cm/s at t t2 0.583 s? N Submit 4) At time t-t3 0.473 s, what is 13, the induced current in the loop? 13 is defined to be positive if it is in the counterclockwise direction

Answer 1

At time t-t'=0.03 s '(hdis 1', the hduced curert in the br I, is delined to be positive Htis in the counterclockise rec 1-0.oaao A At time t n the loop I, s defined to be positive fit is in the coonte -clock wise direction Wha& is fret) ,tie nt of the roe thd nust be orplied to the op tmtan ts onstant velodt u v X- Compone F o.oou5 N At time 4-t 3 3, what is Ta, the induced current tn the loop ? 1s is defined to be gositive f s in the ourterclock wise direction I -o.oaa A
