Question

How would you describe the interaction between opposite (N-S or S-N) magnetic poles?
Dont they repel??

Answer 1

poles repel the same pole - North repels north, south repels south.

So North is attracted to south, south attracts north.

Answer 2

just think of fridge magnets, when you put the sides that stick to the fridge they repel. that is because the fridge is like a north and the magnets are like the south.

Answer 3

That analogy is not correct.

Every magnet you interact with on a daily basis has two poles: a north and a south pole. Fridge magnets are permanent ferromagnets, and their magnetic field is generated by the alignment of their internal magnetic domains. A magnet sticks to a fridge not because the "fridge's pole" is opposite in sign to the "magnet's pole" - the magnet always has two poles - but rather because the magnetic domains in the iron/steel of the fridge door align with the magnetic field created by the permanent magnet, creating a 'new magnet" in the region it touches on the fridge. Both the north and south pole of a magnet will stick to a fridge, as will the side of the magnet containing both north and south poles.
