## Homework Statement

Copy the diagrams in Figure 7 into your notebook, and draw the direction of the conventional current or the

magnetic field lines. Also indicate the location of the north and south poles where appropriate.

**FIGURE 2**

## Homework Equations

## The Attempt at a Solution

__Using conventional flow (+ve →-ve)__

Firstly, would I be correct in assuming that both Figure 1 and Figure 2 would produce the same magnetic field lines? Because using the right hand rule (which my book uses), a current going out of the page (left circle, figure 1) would produce field lines going counter-clockwise, and into the page (right circle, figure 1) is clockwise using the right hand rule. So would the two be the exact same?

What I can't seem to figure out is which way is north. I know how to determine north in a solenoid, but I'm not sure how to determine it for just two currents. Is there a north/south? We weren't taught this in class, and it doesn't seem to be in my textbook.

Thanks for any help.
