Q2. The magnetic circuit shown in Figure Q2 is made of high permeability steel so that its reluctance can be negligible. The dimensions are as follows: N =1200, g = 2 mm, l = 15 cm, and i = 10 Adc.
(i) Derive an expression for flux density in the air gap, Bg, as a function of dimensions and magnetic field quantities.
(ii) Derive an expression for the inductance, L, in the two air gaps.
(iii) Find the force, Fm, on the moving part using (i) and (ii).
(iv) If the maximum flux density, Bmax, is to be limited to 1.6 T, determine Fm(max).
Pls help,,,,,,,
