The rule that determines the direction of a magnetic field produced around a straight conductor carrying current is:
Right-hand thumb rule
The correct rule for determining the direction of the magnetic field around a current-carrying conductor is the "Right-hand thumb rule", where the thumb of your right hand points in the direction of current and your fingers curl in the direction of the magnetic field.
