Question
For each situation shown in the table that follows, predict if a current is induced through the resistor attached to the loop. If a current is induced, indicate the direction of that induced current.
18.2.1 Reason For each situation shown in the table that follows, use the rules devised and tested in Section 18.1 to predict if a current is induced through the resistor attached to the loop. If a current is induced, indicate the direction of that induced current. Experiment Predict if a current If you predict that a is induced; explain current is induced your prediction. what is the direction of the current? (a) The loop is perpendicular to the page (b) The loop is perpendicular to page and the magnet turns 90 (c) The loop is in the plane of the page. (d)The loop, perpendicular to page, is pulled upward so that it collapses. Pull up stationary e) The switch in the left circuit is closed and the current increases abruptlyExplanation / Answer
Solution:
Experiment a)
Yes, a current is induced. Flux increases.
The direction of current is: counterclockwise
Experiment b)
Yes, a current is induced. Flux decreases
The direction of the current is: clockwise, after rotated 180 º current will be counterclockwise.
Experiment c)
No, no flux
Experiment d)
Yes, a current is induced. Flux decreases.
The direction of current is: counterclockwise
Experiment e)
Yes, a current is induced. Flux increases while switched is on.
The direction of current is: Clockwise
Experiment f)
No. Flux does not change
Experiment g)
Yes, a current is induced. The Flux decreases.
The direction of current is: counterclockwise.
Experiment h)
Yes, a current is induced. The Flux decreases.
The direction of current is: counterclockwise.
