Asmall airplane of a wingspan of 14.0 m is flying due north at a speed of 70.0 m/s over a region where the vertical component of the earth's magnetic field is 1.2 μt downward. (a) what potential difference is developed between the airplane's wingtips? (b) which wingtip is at higher potential? (c) what if? how would the answers to parts (a) and (b) change if the plane turned to fly due east? (d) can this emf be used to power a lightbulb in the passenger compartment? explain your answer
