A spotlight shines onto a square target of area 0.35 m2. If the average (rms) strength of the magnetic field in the EM waves of the spotlight is 1.2 x 10-7 T, calculate the energy transferred to the target if it remains in the light for 12 minutes. (Give your answer in joules but don't include the units.)
