Dushyant Singh from Shree Ram Centenial School, Indore

see the solution the magnet gets in contact with q so it is the correct ans

Ans 2:

Class :
N POLE ALWAYS GIVE THAT'S WHY A

Ans 3:

Tejas Singh from Freedom International School, Bangalore
Class : Class 6
I didnt understand how it is R, can someone explain? Because according to me, the first point of contact is Q, but maybe that's not how it works....

Ans 4:

malhar thorve from city internqtional school, satara road, pune
Class : Class 7

Ans 5:

Aadhira from velammal new gen school, Medavakkam, Chennai
Class : Class 6
The correct answer is (B),Q because the magnetic contact starts on Q and not on P.

Ans 6:

Shuvangi Das from Vivekananda mission school, haldia
Class : Class 9
Will P be the North Pole or Q? So confusing!!🤔🤔

Ans 7:

Devavrat Sharma from Podar International School Powai, Mumbai
Class : Class 7
The correct answer is (B) because Q is the first point of contact.

Ans 8:

Mohit Shekher from ST Andrews School, Secunderabad
Class : Class 7
In the above process of magnetisation, the magnet makes its first contact with the iron rod on place R, so R would be the North pole of the magnetised iron bar.

Ans 9:

PAYAL from DPS BHILAI, BHILAI
Class : Class 8
it has started magnetising from Q SO THATS WHY IT IS TELLING THAT Q WILL BE THE NORTH SEEKING POLE.

Ans 10:

Ashmi Narkar from The Shishukunj International School, Jhalaria Campus, Indore
Class : Class 9
Q or R?????? PLEASE EXPLAIN MASTER ANSWER!

Ans 11:

Vivaan Kumar from Heritage Xperiential Learning School, Gurgaon
Class : Class 8
B IS A WRONG ANSWER.

Ans 12:

ADVAY BANSAL from LOTUS VALLEY INTERNATIONAL SCHOOL GURUGRAM, GURUGRAM
Class : Class 8
As north seeking pole is geographic south pole so R is north seeking pole. so , basically the south pole is the north seeking pole and as the north pole is facing downwards and starting with Q so south pole will be R . Hence, R is the north seeking pole and option C is the correct option.

Ans 13:

Ayansh Mallick from Birla Open Minds, Hyderabad
Class : Class 8
A

Ans 14:

Jigishal Thool from Don Bosco School, Guwahati
Class : Class 6
AS NORTH POLE INTRODUCED AT Q PART OF THE IRON ROD SO Q WILL BE NORTH POLE.

Ans 15:

Shreeya Mangla from ASN Senior Secondary School, New Delhi
Class : Class 9
At first, I also thought that it will be A but if you see the figure closely, you can see that the magnet first comes in contact with point Q, it is rubbed till R and is then lifted at R point. So, Point Q would be the north pole and the point R would be the south pole

Ans 16:

Navya from Gyanshree, Noida
Class : Class 6
IT WILL BE P!

Ans 17:

Mohit Shekher from ST Andrews School, Secunderabad
Class : Class 7
Sorry R would be the south pole because of the reason:Q becomes the North pole, and R, where the magnet is lifted becomes the south pole.

Ans 18:

Sharanyaa Tripathi from Uttam school for girls, Ghaziabad
Class : Class 8
If you clearly notice, the arrow is first coming in contact with Part Q, and the arrow is above in Part P. First, the magnet comes in contact with part Q, so when the iron rod is magnetised, Part Q will be North pole.

Ans 19:

Veda Dua from Delhi Public School, R. K. Puram, New Delhi
Class : Class 10
The magnet first makes contact with Q, so, it is the North Pole of the magnet

Ans 20:

from ,
Class :
The poles are end point of the magnet ,so the north pole should be P.

Ans 21:

Ayansh Mallick from Birla Open Minds, Hyderabad
Class : Class 8
The answer is P as you can clearly see the iron rod should allow the magnetism to flow like what happens when you chain a nail, even though you are affecting only the top part the whole screw is affected hence proving the answer is wrong

Ans 22:

Manya Pujar from EuroSchool, Davangere
Class : Class 6
A IS TH CORRECT ANSWER. In the figure they started stoking the iron piece from point P which is the starting of the iron rod. so the correct answer is A.....

Ans 23:

Shaurya from Mris 51 Gurugram, Gurugram
Class : Class 7
it will be P!!!!!!!!!!!!!

Ans 24:

Tamrashi Pani from National Public School, Bangalore
Class : Class 8
I agree with jigishal

Ans 25:

Shourya Ganesh from The Green Acres Academy, Mumbai
Class : Class 9
It should be a

Ans 26:

Tamrashi Pani from National Public School, Bangalore
Class : Class 8
The answer is B

Ans 27:

Ayansh Mallick from Birla Open Minds, Hyderabad
Class : Class 8
A

Ans 28:

Ashwak from Cambridge, Jalandhar
Class : Class 9
Yes it should be A ......because it is not possible that some of the iron bar is magnet and some is iron ....in the given figure starting of the stroke is point is Q but before that is point P which is starting of the rod so the CORRECT answer is A ..

If the filament of bulb Q is fused then the circuit is not being completed because the electrons won't be able to reach the positive terminal as they would be stopped by the broken filament and electricity won't be able to pass through the filament to the negative terminal and due to the two cases that a circuit has to be completed for electricity to move and second one given it is proven that option 'B' is the correct option instead of 'A' 'C' or ' D'
