उत्तर
This rule is used to determine the direction of magnetic field lines around a straight current-carrying conductor.
For example, if the current flows vertically upwards in a wire, the magnetic field lines will be in an anticlockwise direction. If the current flows downwards, the field lines will be clockwise.
