What is the source of a magnetic force in a current carrying wire?

If the direction of electric current is reversed, then the direction of the magnetic field would also be reversed.

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. Draw a diagram representing the construction of this equipment.
