Study the magnets X and Y given below:

(a) If B is the north pole of the magnet X, which is the north pole of magnet Y?
(b) What will happen when A is brought close to C?

Look at the table given below:

Which parts of the magnet are the poles?

Study carefully the following magnets. 

What type of magnetic pole is (a) X, and (b) Y?

Anhad puts a car on an aluminium sheet. He then placed a magnet under the aluminium sheet as shown in the diagram below. When he moved the magnet, the car also moved.

(a) What material is the car made of?

(b) What does this activity tell us about aluminium?

Magnet A is floating above magnet B as shown in the following diagram. What is the reason for this?

Observe the given figure and identify the correct statements.

(I)  Poles $1,3$ and $5$ are unlike poles.
(ii)  Poles $2,4$ and $6$ are like poles.
(iii)  Pole $1$ will attract pole $3$ and $5$.
(iv)  Pole $4$ will be attracted by pole $1$.

When Asha suspended four bars of different materials from a pole and brought the North pole of a bar magnet near part $P$ and $Q$ of each bar one by one as shown in the figure, the observations she recorded are as follows: 

Which of the following sets correctly represents metal bars $\mathrm{I},\mathrm{}\mathrm{I}\mathrm{I},\mathrm{}\mathrm{I}\mathrm{I}\mathrm{I}$ and $\mathrm{I}\mathrm{V}$?
