Appliances with higher power ratings are connected to which ampere line (in $A$)?

The diagram below shows a coil connected to a centre zero galvanometer $G$. The galvanometer shows a deflection to the right when the $N$ pole of a powerful magnet is moved to the right as shown.
$(i)$ Explain why the deflection occurs in the galvanometer.
$(ii)$ Does the direction of current in the coil appear clockwise or anticlockwise when viewed from end $A$?
$(iii)$ State the observation in $G$ when the coil is moved away from $N$.
$(iv)$ State the observation in $G$ when,both coil and the magnet,are moved to the right at the same speed.

For a current in a long straight solenoid,$N-$ and $S-$ poles are created at the two ends. Among the following statements,the incorrect statement is:

Mention the angle between a current-carrying conductor and a magnetic field for which the force experienced by this conductor is maximum. (in $^{\circ}$)

What is meant by the term "magnetic field lines"? List two properties of magnetic field lines.

Inside a current carrying solenoid,the magnetic field lines are:
