Question: A coil has Na turns enclosing an area of A. In a physics laboratory experiment, the coilis rotated during the time interval Δt from a position in which the plane of each turn is perpendicular to Earth's magnetic field toone in which the plane of each turn is parallel to the field. Themagnitude of Earth's magnetic field at the lab location is B.

a) What is the total magnitude Φinitial of the magneticflux through the coil before it is rotated?

b) What is the magnitude ΦFinal of the total magneticflux through the coil after it is rotated?

c) What is the magnitude of the average emf induced in the coil?
