Magnetic Field Strength (H) gives the quantitative measure of strongness or weakness of the magnetic field. H = B/μo Where B = Magnetic Flux Density μo = Vacuum Permeability Magnetic field due to infinite Linear current-carrying conductor is B = μoI/2πr B/μo = I/2πr H = (I/2πr)A/m
A nuclear power plant is a steam turbine plant where steam is generated by a nuclear reactor. Nuclear energy is the energy that is trapped inside each atom. Nuclear energy is obtained by fission of uranium-plutonium or thorium or the fusion of hydrogen into helium. In normal conditions, the energy released due to the disintegration of a uranium atom is significantly low. The capturing of neutrons by the uranium-235 is rather easy and to fission it for the release of the energy. In a chain reaction, particles released by the splitting of the atom strike other uranium atoms and split them. The particles released by this further split other atoms in a chain process. The chain reaction gives off heat energy. This heat energy is used to boil heavy water at the core of the reactor.
Galvanized steel conductors do not corrode, and possess high resistance. Hence such Wires are used in telecommunications circuits, earth wires, guard wire, stray wire, etc.
