    Find the direction of the magnetic field at point P.

    2. Relevant equations

    See below.

    3. The attempt at a solution

    From the right hand rule, my thumb would point in the current's direction. Thus, my fingers would curl inward, so the magnetic field would point into the page?

    Thanks.

    You can also use another variation. Try pointing your thumb into the page and look at where your fingers point
