When using the right-hand rule for a current-carrying straight wire, the fingers of your right hand point in the direction of the current, and the direction in which your palm faces indicates the direction of the magnetic field lines that encircle the wire. Therefore, the part of the right hand that points in the direction of the magnetic field is the palm.
