PHY 102 Electromagnetic Induction 2 Objective Question
Take CBT

Question

Which of the following actions would NOT lead to an increase in the electromotive force (EMF) induced in a coil?
Options
A Increasing the number of turns in the coil.
B Decreasing the magnetic field strength surrounding the coil.
Correct Answer
C Increasing the speed of the relative motion between the coil and the magnet.
D Increasing the magnetic flux, assuming the rate of change is positive.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 12 explains that increasing turns, magnetic field strength, or speed of relative motion increases induced EMF. Decreasing magnetic field strength would decrease the change in flux, thus decreasing the induced EMF.

Hint

Recall the factors that directly contribute to a larger rate of change of magnetic flux.
