PHY 102 Electromagnetic Induction 2 Objective Question
Take CBT

Question

According to the text, how can the induced electromotive force (EMF) in a coil be increased?
Options
A By decreasing the number of turns in the coil
B By increasing the number of turns in the coil
Correct Answer
C By decreasing the magnetic field strength
D By reducing the speed of relative motion between the coil and magnet
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 12 explains: 'By increasing the number of turns in the coil i.e N, from the formulae derived above it is easily seen that if the number of turns in a coil is increased, the induced emf also gets increased.'

Hint

Consider the variables in Faraday's law that contribute to the magnitude of the induced EMF.
