Inductance & magnetic flux problem -- please help
The magnetic field of a place on Earth has strength 55 microTesla and is tilted 60 degrees below horizontal. A 200 turn coil with diameter 4cm and resistance 2 ohms is connected to a 1 microFarad capacitor. The coil is held in a horizontal plane and the capacitor is discharged. Then quickly the coil is rotated 180 degrees. Afterwards, what is the voltage on the capacitor?
I have the flux through the coil initially:
= pi* (.02)^2 * (5.5e-5) * cos (30) * 200 = 1.2 e -5 Wb
But I really don't understand what happens when the capacitor discharges. Also, how does just flipping the loop over will change the flux to induce a current? It seems to me that the angle doesn't change or anything. Please help.
