Problem
A straight copper conductor 25cm long carries a current of 150mA and is held perpendicular to a uniform magnetic field of 0.40T in a laboratory experiment.
(i) Convert the given length and current to proper SI base units before carrying out any calculation.
(ii) Calculate the magnitude of the force acting on the conductor.
(iii) Express your final answer using two significant figures.
