Can you please have look at the attached file. I am having difficulty with Q6 part (iv), not sure if i have the correct answer! I derived the expression from part (iii) and found; E1/N1 = E2/N2 = 4.44fϕ. I used the expression in part (iv) to get E2 = 1300 volts and Area = 6.00 x 10^-3 m^2. I used another method to check my answer, e.m.f = N. dϕ/dt = N.B.A.ω (where, ω = radian frequency) Found Area = 4.24 x 10^-3 m^2 !!! Any help is greatly appreciated.
