Question

In a physics laboratory experiment, a coil with 190 turns enclosing an area of 12.4 cm2 is rotated in a time interval of 3.90 times 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 6.1 times 10^-5 T What is the total magnetic flux through the coil before it is rotated? Express your answer using two significant figures. What is the total magnetic flux through the coil after it is rotated? Express your answer using two significant figures. What is the average emf induced in the coil? Express your answer using two significant figures.

Explanation / Answer

A)When plane is perpendicular to the earth's magnetic field

Flux=Area*magnetic field=12.4x10-4x6.1x10-5=7.56x10-8Tm2

B)When plane is parallel to the earth's magnetic field

Flux=0

C)average emf=-7.56x10-8/3.9x10-2=-1.94x10-6volts
