A semicircular loop of radius R is rotated with an angular velocity ω perpendicular to the plane of a magnetic field B as shown in the figure. Emf induced in the loop is (1) BωR 2 (2) 1 2 B ω R 2 (3) 3 2 B ω R 2 (4) 1 4 B ω R 2

A semicircular loop of radius R is rotated with an angular velocity ω perpendicular to the plane of a magnetic field B as shown in the figure. Emf induced in the loop is

(1) BωR ² (2) $\frac{1}{2} B ω R^{2}$ (3) $\frac{3}{2} B ω R^{2}$ (4) $\frac{1}{4} B ω R^{2}$
