Application: The MHD generator. A small magneto hydrodynamic (MHO) generator is proposed as part of the exhaust system of a jet engine. The MHD channel is 200 mm by 200 mm in cross section and is 1 m long. A magnetic field of 1 T is generated between two surfaces as shown in Figure 10.52. The exhaust moves at 200 m/s and is seeded to produce a conductivity of 50 S/m in the channel. Calculate:
(a) The output voltage of the generator. Show polarity.
(b) The internal resistance of the generator.
(c) Maximum power output to a load under maximum power conditions.
