An airplane flies level to the ground towardthe north pole. (a) Is the induced emf from wing tip to wing tipwhen the plane is at the equator greater than, less than, or equalto the wing-tip-to-wing-tip emf when it is at the latitude of NewYork? (b) Choose the best explanation from among the following:I. The induced emf is the same because the strength of theEarth’s magnetic field is the same at the equator and at NewYork.II. The induced emf is greater at New York because the verticalcomponent of the Earth’s magnetic field is greater there thanat the equator.III. The induced emf is less at New York because at the equator theplane is flying parallel to the magnetic field lines
An airplane flies level to the ground toward
the north pole. (a) 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? (b) Choose the best explanation from among the following:
I. The induced emf is the same because the strength of the
Earth’s magnetic field is the same at the equator and at New
York.
II. The induced emf is greater at New York because the vertical
component of the Earth’s magnetic field is greater there than
at the equator.
III. The induced emf is less at New York because at the equator the
plane is flying parallel to the magnetic field lines
