Question
Figure a-ho s a octan guar conducting oop o as stanca R = 0.0320 ? height H 1.5 cm, a d langth D 5.7 cm be ng pulla t constant spoed v = 54 cm's through two rec ons of un o m ma posit omx of the right side of the loop. The vertical exis scale s set by 5.4 ?? Fer example e cu rent equel to is induced clock ise es the loop enters egion 1 What 8 e the a egnitude end direction of the magnetic field in region 2? e c eld Figure gve: the current inducoc n the loop as a function of the b drection of the meg etic ed in eg 1? what 8 e the c) ag itude 8 d a) (bj (djExplanation / Answer
induced emf, e = v*B*H
induced current Is = e/R = v*B*H/R
5.4*10^-6 = 0.54*B*0.015/0.032
B = 21.3 uT

region 2
induced emf, e = v*B*H
induced current I = (2/3)*Is = e/R = v*B*H/R
(2/3)*5.4*10^-6 = 0.54*B*0.015/0.032
B = 14.2 uT
