Answer 1

what the fact is the magnet poles are individual for every piece so there are 10 north poles and if you put it in a bar magnet you can get there poles because of the repulsion and attraction property of magnet

Answer 2

a)10
b)1
to demarcate the poles of a magnet we should place an already marked magnet near to it by facing either of the poles to the magnet that should be marked like for example face the north pole to the magnet if it attracts then it's south pole if it repels it is north pole
