Find the true statement.

(a) The force on a current carrying conductor in a perpendicular magnetic field is due to the thermal energy dissipated

(b) The force on a current carrying conductor in a perpendicular magnetic field is due to the mechanical energy dissipated

(c) The force on a current carrying conductor in a perpendicular magnetic field is due to the current passing through it

(d) The force on a current carrying conductor in a perpendicular magnetic field is due to the electrical energy initially converted from mechanical energy

Right option is (d) The force on a current carrying conductor in a perpendicular magnetic field is due to the electrical energy initially converted from mechanical energy

To explain: The force on a current carrying conductor in a perpendicular magnetic field is due to drift velocity of charges along the current carrying conductor and the consequent Lorentz force acting on it. So, it is due to the electric energy which was the energy that mechanical energy dissipated in the system was initially converted to.
