For the circuit given in Fig. Q2: a = 2 cm (core thickness), b = 14 cm and c = 16 cm. The air-gap length is 0.5 cm. The core cross sectional area is 8 cm?. The coil has 200 turns. The coil arm (with different colour: brown) is made of sheet steel (relative permeability = 5500) while the rest of the core is made of cast iron (relative permeability - 4800). The magnetic flux density at the air-gap is 0.8 T. Use the magnetisation curves in Fig Q2-b to calculate the following:

![For the circuit given in Fig. Q2: a = 2 cm (core thickness), b = 14 cm and c = 16 cm.
The air-gap length is 0.5 cm. The core cross sectional area is 8 cm?. The coil has
200 turns. The coil arm (with different colour: brown) is made of sheet steel (relative
permeability - 5500) while the rest of the core is made of cast iron (relative
permeability - 4800). The magnetic flux density at the air-gap is 0.8 T. Use the
magnetisation curves in Fig Q2-b to calculate the following:
(a) find I' indicated in Figure Q2.
