    A The iron ring shown in Fig. 1, is made up of a material having a relative permeability of 1000 and has a flux density of 2 T in the air gap. For the given dimensions of l1 = 0.15 m, l2 = 0.1 m, l3 = 0.2 m, lag = 1 cm, A1 = A3 = Aag = 2*10-4 m2, A2 = 3*10-4 m2, if the current through the coil is 1.5 A, compute the number of turns required

    my answer was 11052 turns


    but the answer is 11029 turns. please help
    thanks :)

    I noted you posted the same problem earlier. There is less chance of the thread sinking to the bottom if you post problems like this in the homework forum - irrespective of whether it's homework or not. The only thing is to remember to post your solution when using homework forum otherwise you won't get much assistance.
