Answer the following questions : Study the following principle and answer the questions. 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 magnetic field. Write the working of this equipment in brief.
