Answer published by the source. Consult the official source to check your work against its answer.
question
Atoroidaltype of magnetic core of rectangular cross section hasthe following parameter values: l_m= 20 cm, A_m = (2 cm) (1 cm) = 2 cm^2, l_g= 0.1 cm,\mu_r= 4000. Determine the ampere turnsiNrequired to realize a magneticflux density in the air gap of magnitude B_g= 0.1Wb/m^2. The air-gap area is taken as A_g = (2 + 0.1) (1 + 0.1) cm^2 = 2.31 cm^2.
