Thanks! Hesch. I have one question. The magnetomotive force (Fm) produced from the coil is for the core and the air gap or just for the core only?

What do you mean by the length of the circulation path? And why Hcore = Hairgap / 700 ? Sorry I still don't understand, and I am getting confused with the formula.

Rm = length / μA So, length = 0.1 x10^-3 μ = (μr) (μo) = (700)(4π x 10^-7) A = 0.003 I followed the formulas given to me.

Fm = (500)(10/27) = 185.185 At Total flux = βA = (0.35)(0.003) = 0.00105 wb Rm = Fm / total flux = 185.185 / 0.00105 = 176366.6667 At/wb R(air) = (0.1 x10^-3) / (700)(4π x 10^-7)(0.003) = 37.894034 At/wb Rm = length / μA length = Rm...
