A circular loop of wire with 330 turns, radius 15.0 cm, and resistance 4.00 Ω held in a horizontal plane. Also shown is the Earth’s magnetic field which points north and down at an angle of 50.0° and has magnitude 55 µT. (a) Find the initial magnetic flux for a single turn of the coil. The coil is now rotated 50.0 ° so that the flux drops to zero.
