Magnetic flux and induced emf

Question

As shown in the figure, a magnet is moved with a fast speed towards a coil at rest. Due to this induced electromotive force, induced current and induced charge in the coil is E,I and Q respectively. If the speed of the magnet is doubled, the incorrect statement is

Moderate

A

E increases
B

I increases
C

Q remains same
D

Q increases

Solution

Induced charge doesn’t depend upon the speed of magnet.
