Question
please just show the steps on how to do the problem Iwould like to solve it my self A magnetic field passes through a stationary wire loop, andits magnitude changes in time according to the graph in thedrawing. The direction of the field remains constant, however.There are three equal time intervals indicated in the graph:0 – 3.0 s, 3.0 – 6.0 s, and6.0 – 9.0 s. The loop consists of 40 turns ofwire and has an area of 0.18 m2. The magnetic field isoriented parallel to the normal to the loop. For purposes of thisproblem, this means that = 0° inEquation 22.2. (a) For each interval, determinethe induced emf. (b) The wire has a resistance of0.50 . Determine the induced current for thefirst and third intervals.
Explanation / Answer
No.of truns N = 40
Area A= 0.18 m ^ 2
(a). Induced emf in 0-3 s is E = NA dB / dt
= 40 * 0.18 * ( 0.4 / 3 )
= 0.96 Volt
Induced emf in 3 -6s is E = NA dB / dt
= 40 * 0.18 * ( 0 / 3 )
=0 Volt
Since change in magnetic field dB = 0
Induced emf in 6-9 s is E = NA dB / dt
= 40 * 0.18 * ( -0.2 / 3 )
=-0.48 Volt
