PHY 102 Electromagnetic Induction 2 Objective Question

Question

If a magnet is moved 'away' from a coil connected to a galvanometer, how does the galvanometer needle typically behave compared to when the magnet moves 'towards' the coil?
Options
A It remains at zero.
B It deflects in the same direction.
C It deflects in the opposite direction.
Correct Answer
D It shows a larger deflection.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 5 explains, 'Likewise, when the magnet is moved 'away' from the coil in the other direction, the needle of the galvanometer deflects in the opposite direction with regards to the first indicating a change in polarity.'

Hint

The direction of induced current depends on the direction of change in magnetic flux.
