A coil has 180turns enclosing an area of 13.9 cm² . In a physics laboratory experiment, the coil is rotated during the time interval 0.050 s from a position in which the plane of each turn is perpendicular to Earth's magnetic field to one in which the plane of each turn is parallel to the field. The magnitude of Earth's magnetic field at the lab location is 5.7010⁵ T.

part A-What is the magnitude of the magnetic flux through one turn of the coil before it is rotated?Express your answer in webers.

part B- What is the magnitude of the magnetic flux through one turn of the coil after it is rotated?Express your answer in webers.

part C - What is the average emf induced in the coil as it is rotated from the perpendicular to the parallel orientation?

Thank you very much in advance.
