Sen 1.4
Two coils are wound on a toroidal core as shown in Fig. P1.4. The core is made of silicon sheet
steel and has a square cross section. The coil currents are i₁ = 0.28 A and i₂ = 0.56 A.
(a) Determine the flux density at the mean radius of the core.
(b)
Assuming constant flux density (same as at the mean radius) over the cross section of the
core, determine the flux in the core.
(c) Determine the relative permeability,
, of the core.
