(4%) Problem 5: Joe has rolled a long electrical extension cord into a coil of radius rc = 11 cm with N = /1 loops. The coil of extension cord is initially lying horizontally (flat) on the floor of Joe's garage. Joe picks up the coil and rotates it 90 in t, = 0.65 seconds so that the coil is now vertically oriented (see the figure). J A 33% Part (a) If the Earth's magnetic field has strength 0.50 gauss and makes an angle of 20.0 degrees with the garage floor, calculate the change in the magnetic flux 4, in Wb, through one of the loops of the coil during the rotation.
