EXERCISE 29.2

In a physics laboratory experiment, a coil with 240 turns enclosing an area of 10.8 cm2 is rotated in a time interval of 3.80×10−2 s from a position where its plane is perpendicular to the earth's magnetic field to one where its plane is parallel to the field. The earth's magnetic field at the lab location is 6.5×10−5 T. (Express your answers using two significant figures.)

A) What is the magnetic flux through each turn of the coil before it is rotated?

B) What is the magnetic flux through each turn of the coil after it is rotated?

C) What is the average emf induced in the coil?
