Question

Figures show two iron nails each hanging from a bar magnet and U - shaped magnet. 1) choose the correct figures 2) explain the reason for choosing these figures​

Answer 1

First case, the correct figure is the third one

Second case, the correct figure is the second one

Explanation:

• We know that like poles repel and unlike poles attract each other

• In the first case the correct figure is the third one as the flat end of the nails is attached to the North pole thus this end of the nail will behave as North pole while the free end will behave as South pole

• The free end (pointed end) will repel each other as they are both South poles, thus there will be distance between them

• Hence third figure is correct

• In the second case the second figure is the correct one as the flat end of the nails are connected to different poles so for first nail the flat end will behave as North pole while for the second nail, the flat end will behave as South pole

• As a result, the free end (pointed end) will behave like a South pole for the first nail and North pole for the second nail

• Thus, the pointed end of both the nails will attract each other and the distance between them will decrease

Hope this answer is helpful.
