Find the EMF

It should equal U_o*V*L*I/2*pi*r, but how do I get there?

Hi and welcome to PF!

I'd use Faraday's law of induction.

E = -d/dt*(Flux B)

E = -d/dt * BLR

E = dr/dt * -BL

E = -BLV

E = -u_o*I*V*L / 2*pi*r

Why does the negative go away for the correct answer?

I wish you the best of the luck for your exam. I'm taking the final exam on Friday .

I'd appreciate if someone could tell us if you did it properly and why is there this minus sign...

Let's wait.
