In the given circuit the maximum deflection in the galvanometer occurs when
- a)magnet is rotated inside the coil
- b)magnet is stationary at the center of the coil.
- c)numbers of turns in the coil is reduced.
- d)magnet is pushed into the coil.
Correct answer is option 'D'. Can you explain this answer?

In the given circuit the maximum deflection in the galvanometer occurs...
This question based on lenz law. as the bar magnet is moving , there is a change in magnetic flux.This will give polarity in the coil. Hence the current developed in the coil. so the option d is right.

In the given circuit the maximum deflection in the galvanometer occurs...
The correct option for this question is D.Now i am going to tell you ,how a, b and c are wrong with respect to option d.
firstly this question is based on lenz law which states that changing magntuc flux induces current in the coil.
For A option-We know that magnetic field around the bar magnet is symmetric in nature.So if we rotate this magnet inside coil,there is no change in magnetic flux through the coil,so current is not indued in the coil.so no deflection in galvnometer.
For option B-When magnet is stationary , there is no changing in magnetic field,hence no current is induced.
For option C- As we know that current induced in the coil is directly proportinal to the number of turns in the coil.More the number of turns,more the current and more will be the deflection in the galvanometer but here we are reducing the number of turns in the coil.so current will deceases and ultimately deflection in galvanometer also decreases.
For option D-Magnet is pushed into the coil,so there is change in magnetic field and magnetic flux also changes and current gets induced in the coil.So in this case we see the maximum deflection in the galvanometer.
