Problem
A conductor placed perpendicular to a uniform magnetic field experiences a force F when it carries a current I along its whole length L. If the current is doubled while the magnetic field strength is reduced to one-third of its original value and L remains unchanged, what will be the new force on the conductor in terms of F?
