MY NOTES ASK YOUR TEACHER A rectangular loop of length L and width W is placed in a uniform magnetic field B with its plane perpendicular to the field (see figure below). Determine the time-averaged induced emf if the loop rotates with constant angular velocity w through an angle of 180 around an axis passing through the loop's center in the following orientations. (Use the following as necessary: B, L, W, and w. Enter the magnitudes.) O o w 10 O O O Axis of rotation Axis of rotation A. B.

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER 2 Suppose a uniform magnetic field is perpendicular to the 8- x 11-in. page of your homework and a rectangular metal loop lies on the page. The loop's sides line up with the edges of the page. The magnetic field is changing with time as described by B = 8.20 x 10-3 t, where B is in teslas and t is in seconds. (a) Is the magnetic field increasing or decreasing? O increasing O decreasing (b) Find the magnitude of the emf induced in the loop. V Submit
