AB is a current carrying conductor in the plane of the paper as shown in figure. What are the directions of magnetic fields produced by it at points P and Q?

into the plane of paper at point Q and out of it at point P into the plane of paper at point P and out of it at point Q into the plane of paper at points P and Q  out of the plane of paper at points P and Q

into the plane of paper at point P and out of it at point Q

Applying the right hand thumb rule, the direction of magnetic field would be anti-clockwise as shown in diagram around the direction of current.
