7. A square loop is placed in a uniform magnetic field perpendicular to the plane of the loop as shown. The loop is 0.50 meters on a side and the magnetic field B has a strength of 2 T . If the loop is rotated through an angle of 90∘ in 0.1 second what would be the average induced EMF in the loop?
(A) 0.025 C
(B) 0.40 V
(C) 5 V
(D) 10 V
