If a bar magnet's head '1' is brought closer to another bar magnet's head '2', it was observed that they repel each other. What can be the poles of part 1 and part 2?
1-North, 2-North
1-South, 2-South
We know that like poles repel each other and unlike poles attract each other. Since it was observed that the parts 1 and 2 repel each other, so, they can be either south-south or north-north poles.
