A wire loop enclosing a semi-circle of radius r=1 mr = 1 \text{ m} is located on the boundary of a uniform magnetic field of induction B=2TB = 2T. At the moment t=0t = 0 the loop is set into rotation with a constant angular acceleration α=3 rad/s2\alpha = 3\text{ rad/s}^{2} about an axis OO coinciding with a line of vector BB on the boundary. Find the magnitude emf induced (in Volts) in the loop at t=2 sect = 2\text{ sec}.

(You can ignore self-inductance effects.)
