An ac generator consisting of a coil with n turns rotating at angular speed ω in an external magnetic field b produces a maximum emf ε0.if you now decrease the number of turns in the coil to n/2 and at the same time cause it to rotate twice as fast, what will be the new maximum emf if you do not change any of the other quantities?
