What is the potential difference between the tips of the wings? ume that the wings are made of aluminum.?

A supersonic aircraft with a wingspan of 6.5 m is flying over the north magnetic pole (in a magnetic field of magnitude 52.3 μT perpendicular to the ground) at a speed of 3.07 times the speed of sound (Mach 3.07, vsound = 340.0 m/s). What is the potential difference between the tips of the wings? ume that the wings are made of aluminum.
