Now refer to part ii of this question and think about the current direction produced in the coil, and the magnetic flux produced (by induced current in the coil's loop). Once you get the idea of Lenz's Law (in the electromagnetic induction), what do you think of the direction of current in the wire (bottom of the figure)? Right to left or left to the right? You can just write Right to Left or Left to Right.

i.
The magnet is pushed avway from the solenoid. What will be the magnetic field
direction inside the coil? Just write your answer as Left to right or Right to Left.
Left to right
Write the Lenz's Law in Electromagnetic Induction. Make sure that you have
clearly understood the concept of Lenz's law.
ii.
The current induced in a circuit due to a change in a magnetic field is directed to
oppose the change in flux and to exert a mechanical force which opposes the
motion.
iii.
When the magnet is pushed away from the coil, what do you think the magnetic
field strength (magnetic flux) in the coil's loop? Is it increasing or decreasing?
Decreasing
iv.
Now refer to part ii of this question and think about the current direction produced
in the coil, and the magnetic flux produced (by induced current in the coil's loop).
Once you get the idea of Lenz's Law (in the electromagnetic induction), what do
you think of the direction of current in the wire (bottom of the figure)? Right to
