How is the relative strength of a magnetic field shown around a magnet?

Make a table with names of three electrical appliances used in your home in one column, their power, voltage rating, and approximate time for which each is used in one day in the other columns.

On what factors does the force experienced by a current-carrying conductor placed in a uniform magnetic field depend?

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.

Draw magnetic field lines produced around a current-carrying straight conductor passing through a cardboard. How will the strength of the magnetic field change when the point where the magnetic field is to be determined is moved away from the straight wire carrying a constant current? Justify your answer.

The magnetic field produced by a current in a straight wire has no poles.
