Question

Given the magnetic circuit, calculate Φ₃ from the right column if the coil wound in the left column has 400 turns and a direct current of 25 A passes through it.

 

Consider a core formed by a stacked magnetic sheet of 0.5 mm thickness and 2.6 W/kg of losses in the iron, measured at a frequency of 50 Hz and an induction of 1 T. Data of useful sections: S1= 200 cm² , S2 = S3 = 100 cm².
