Lenz' law and solenoids.

Hi guise!
In class my teacher conducted an "experiment". This were the results.

What is the deflection of the needle in a galvanometer when:
a.   NORTH pole of the magnet is PUSHED IN the LEFT of the solenoid? Right to left.
b.   NORTH pole of the magnet is PULLED OUT of the LEFT of the solenoid? Left to right.
c.   SOUTH pole of the magnet is PUSHED IN the LEFT of the solenoid? Left to right.
d.   SOUTH pole of the magnet is PULLED OUT the LEFT of the solenoid? Right to left.
e.   NORTH pole of the magnet is PUSHED IN the RIGHT of the solenoid? Left to right.
f.   NORTH pole of the magnet is PULLED OUT the RIGHT of the solenoid? Right to left.
g.   SOUTH pole of the magnet is PUSHED IN the RIGHT of the solenoid? Right to left.
h.   SOUTH pole of the magnet is PULLED OUT the RIGHT of the solenoid? Left to right.

I understand that Lenz' law is: "The induced current will travel in a direction so that the magnetic field it produces opposes the change in flux which induced it." But I dont understand why it occurs. I'll greatly appreciate if you could help me understand.

Thank you for taking your time in reading this.

Please explain further.  So you are asking why Lenz's law occurs as in general or why you got these data?

Both actually LOL.
