Question 1 : Explain the Working of Magneto Hydro Dynamic Generator with sketch. Answer : Magneto hydro dynamic generator also called MHD generator, the principle of MHD generator is based on Faraday's law of electromagnetic induction. The MHD generator is a high efficiency heat engine that converts thermal energy into electrical energy. According to Faraday's rules, when a conductor rotates in a magnetic field, a voltage is produced in it that produces an electric current. MHD generator uses fluid as a solid conductor which is a conductor. It can be a working liquid, ionized gas or a liquid metal. When ionized gas flows through the magnetic field, a voltage is produced in it and this ionized gas behaves like an electric conductor. The gas is used between 2000 ° -3000 ° K temperature. This method of power generation does not contaminate the environment. Installing an M.H.D power generator costs more than a conventional thermal...
