I know this question might be really rudimentary and stupid for y'all but any help would be really appreciated

The magnetic field produced by the current does not have a north or south pole, so what would the compass needle be attracted by?

If a compass is placed above a current carrying wire, why does the compass needle align itself in the direction of the magnetic field produced by the wire?

I'm sorry, but I don't see how this answer is relevant to my question at all. My question is about two closed loops which produce a magnetic field as such:

You can easily buy lead from anywhere. It is a superconductor below 7.25 K

I've always been taught: North poles attract south poles. Yesterday after studying electromagnetism, I've a question to ask. Here's a diagram: In circuits like these, this is how the north and south poles of these electromagnets are defined. Now my question is, is the reason that the South pole...
