Sohan has a bar magnet and three rods, labelled A,B and C and each end of the rod X and Y. He brought the two poles of the bar magnet near each end X and Y of the rods. He recorded the results as follows :
Rod Observations
A X was attracted to the north pole of the magnet but Y was repelled.
B Both X and Y were attracted to the south pole of the magnet.
C When the magnet was brought near X or Y , it had no effect.
Fill in the blanks with a magnet/non-magnetic material/magnetic material.
Rod A - ______
Rod B - _
Rod C - __________

Solution

Magnet : A substance that has the property of attracting iron, steel, cobalt and nickel.
Magnetic Materials : Materials that are attracted by magnets are called magnetic material.
Non-Magnetic Materials : Materials that are not attracted by magnets are called non-magnetic material.
We know that like poles repel each other and unlike poles attract each other.
On filling the blanks we get:
Rod A - Magnet
Rod B - Magnetic
Rod C - Non-Magnetic
