Fig. 13.12
a. A- North, B- South
b. A- South, B- North
C. A- East, B-West
d. A-West, B- East​

Answer 1

Answer:

When a bar magnet is brought near a compass it will not show any directions and it would get damaged

Answer 2

The correct response to the given question is option b: A-South, B- North.

• According to the magnetic field of the earth, the indicated side of the needle points south.
• Like magnetic poles repel one another, while dissimilar magnetic poles attract each other.
• When the bar magnet is brought closer to the needle, it aligns in a straight direction with respect to the bar magnet.
• We can deduce that the end of the magnet marked with the letter 'B' is the north pole because it is near to south pole of the compass needle.
• And the end of the bar magnet labeled with an 'A' is the south pole because it is close to the compass needle's north pole.
• As a result, depending on the alignment of the needle, the attraction property of magnets and compass needle poles can be established.
