Problem
A straight conductor of length L carrying current I is perpendicular to a uniform magnetic field B. The magnetic force on it is F. Determine the new force when the current is doubled, the length is tripled and the magnetic field strength is halved, while the orientation remains unchanged. Express your answer in terms of F.
