उत्तर १

According to Fleming's left hand rule, the force exerted on a current carrying conductor placed in a magnetic field is maximum when the conductor is placed perpendicular to the magnetic field. That is, the direction of the electric current and the direction of the magnetic field are perpendicular to each other.
