Question 1 Two coils are wound on a toroidal core as shown in Figure. The core is made of silicon sheet steel and has a square cross section. The coil currents are \( i_{1}=1 \mathrm{~A} \) and \( i_{2}=2 \mathrm{~A} \). The relative permeability of the core is \( \mu_{r}=2000 \). (a) Determine the flux density in core. (b) Determine the flux in the air gap. Question 2 Draw a developed diagram of a simplex 2-1. 'er lap winding for a 2-pole armaturf in 8 slots. Determine the brushes positions. \[ z 2+8=16 \] With my best wishes for success Course Instructor Prof. Dr. Soliman Mabrouk Sharaf
