Study the following principle and answer the question.
A force is excreted on a current-carrying conductor placed in a magnetic field. The direction of this force depends on both the direction of the current and the direction of the magnetic field. This force is maximum when the direction of the current is perpendicular to the direction of the getic field.
By which law can we determine the direction of the force excreted on the current-carrying conductor?

Explanation

Fleming's left hand rule .
