Left hand rule
1. The palm of the left hand is positioned so that the extended four fingers coincide with the direction of the current in the section of the conductor. 2. After that, the palm is turned around the axis of the conductor until the magnetic field induction vector enters the palm. 3. The thumb is positioned so that it is in the same plane with the rest of the fingers and is perpendicular to them. Then the thumb will show the direction of the Ampere force.
