Sir I realised my mistake of posting 2nd question in the same thread.kuruman said:Look at the picture below. North pole is green and South pole is red. All needles are lined up in the direction of the local external magnetic field. Three of them are identified by arrows. Towards what pole do the needles identified by arrows point? What about the rest of the needles not identified by arrows? Sort it out in your head and tell me.
@kuruman
Continuing with this one, I deeply analysed everything and since the magnetic field is from north to South for both the solenoids. The needle should point in the direction of the magnetic field which is between the two south poles.
So I finally concluded that the green part of my needle is the north pole of the needle.
Could you tell me which (the red or the green part) is the north pole of the magnetized needle?
And is the polarity of my solenoids correctly labelled?
