An airplane flies level to the ground toward the north pole. is the induced emf from wing tip to wing tip when the plane is at the equator greater than, less than, or equal to the wing-tip-to-wing-tip emf when it is at the latitude of new york?

is less than

Explanation:

The imaginary magnetic field lines that is passing through the earth is travelling parallel at the equator.  Therefore at the equator only horizontal component of the magnetic field acts on the aeroplane. Hence, at the equator the induced emf will be minimum or zero because magnetic field will be perpendicular to the normal to the area of the plane.

                But at New York, the induced emf is non zero because the vertical component of the earth's magnetic field will act on the plane.

Therefore, at equator, the induced emf will be lesser than the emf at New York.

i have no idea oh hey
