"When the current flows up the wire, the magnetic field flows out on the left side of the wire and in on the right side of the wire."

Reason: with your thumb pointing along the current (up) the curled fingers show the magnetic field direction around the wire — out of the page on the left, into the page on the right. (If the current is reversed, the field directions swap.)
