Answer:

1. yes

coz magnetism is a property of flowing current.

a magnetic effect is always produced whenever current flows.

2.No,

the poles of a bar magnet has more strength than the center of magnet.

3. thus happens because magnet allign itself with respect to earth's magnetic field. magnets north will allign with earth's geographic north. Earth also possess it's own magnetism.

4. each piece will now act as a new magnet. So, 10 norths and 10 souths in total..

5.yes. coz, repulsion only happens in case of magnet. a magnet never repels an iron bar. so, it's an magnet. when it is repelling the iron bar, ut is actually repelling the north pole of magnet in form of iron bar.

hope u understood everything, if not.. u may ask me anything. please hit heart button if u like the ans.
