In a physics laboratory experiment, a coil with 210 turns enclosing an area of 13cm^2 is rotated 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 rotation takes 4.2×10?2 s . The earth's magnetic field at the location of the laboratory is 6.0×10?5T.
A) What is the total magnetic flux through the coil before it is rotated?
in Wb
B) What is the total magnetic flux through the coil after it is rotated?
in Wb
C) What is the average emf induced in the coil?
in mV
