A coil has 180 turns enclosing an area of 10.4 cm². In a physics laboratory experiment, the coil is rotated during the time interval 0.046 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 5.00×10-5 T. Part A What is the magnitude of the magnetic flux through one turn of the coil before it is rotated?

The magnetic field around the head has been measured to be approximately 3.00x10-8 gauss. Although the currents that cause this field are quite complicated, we can get a rough estimate of their size by modeling them as a single circular current loop 16.0 cm (the width of a typical head) in diameter.
