Question

Answer the following questions:
1. Write any two properties of magnet.
2. Name a magnetic material
3. What are the two ends of a magnet called?
4. Name the natural magnet.​

Answer 1

Answer:

1.Two properties of a magnet are:

(i) A magnet always has two poles: a north pole and south pole.

(ii) Like magnetic poles repel each other and unlike magnetic poles attract each other.

2.Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include the elements iron, nickel and cobalt and their alloys, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone.

3.The end that faces the north is called the north-seeking pole, or north pole, of the magnet. The other end is called the south pole. When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another.

4.A lodestone is a naturally magnetized piece of the mineral magnetite. They are naturally occurring magnets, which can attract iron. The property of magnetism was first discovered in antiquity through lodestones.
