### Question

Two magnets are used to magnetize a soft iron bar PQ as illustrated in the diagram given. The correct polarity at P and Q respectively

A)
S and N
B)
N and N
C)
S and S
D)
N and S

### Explanation:

When a soft iron bar, like PQ in the diagram, is placed near two magnets, it gets magnetized by a process called magnetic induction. In this case, the north pole of the first magnet is facing point P and the south pole of the second magnet is facing point Q.

During the magnetic induction process, the soft iron bar will develop the opposite polarity at the end closest to each magnet. This means that at point P, which is closest to the north pole of the first magnet, a south pole will be induced. Similarly, at point Q, which is closest to the south pole of the second magnet, a north pole will be induced.

Therefore, the correct polarity at P and Q is Option D: N and S.

• The correct answer is D and S-stands for south while N- as in north

• The correct answer is D

• Donald Prince

Because p is representing the north and q is representing south thank you

• The Answer Is D N And S

• D is 💯 correct

• When a MAGNET is made to contact a MAGNETISABLE or FERROMAGNETIC material, the point at which the magnet makes contact with the material becomes OPPOSITELY CHARGED to the Pole of the Magnet making contact. This then create a kind of Magnetic Attraction between the Induced Pole of the Material and the Pole of the Magnet causing the two to attract one another.

Thus, the Correct Answer is Option D.
