Analysis of longitudinal end effects in a Single Sided Linear Induction Motor using Stream Function approach Abstract-This paper presents the analysis of longitudinal end effects in a single sided linear induction motor leading to the calculation of fields and currents in the rotor sheet and propulsion and levitation forces. Such problem can be tackled by vector potential or stream function approach. The present paper adopts the second approach. A second order partial differential equation has been

Lilies of the Field Introduction A novel named "Lilies of the Field" was written by an American author William Edmund Barrett‚ in the year of 1962. With the assistance of the idea from Barrett ’s novel Ralph Nelson made a tremendous movie in 1963. Discussion A small but excellent novel "Lilies of the Field" made into an excellent and educational movie‚ the main subject of the novel and movie is bless the children and creatures even Charles‚ it is a fact that in the twentieth-century there are

An electric field surrounds electrically charged particles and time-varying magnetic fields. The electric field depicts the surrounding force of an electrically charged particle exerted on other electrically charged objects. The concept of an electric field was introduced by Michael Faraday. The electric field is a vector field with SI units of newtons per coulomb (N C−1) or‚ equivalently‚ volts per metre (V m−1). The SI base units of the electric field are kg⋅m⋅s−3⋅A−1. The strength or magnitude

Electricity and magnetism run nearly everything we plug in or turn on. Although it’s something we take for granted‚ it has taken hundreds of years of experimentation and research to reach the point where we flick a switch and the lights go on. Ancient Greeks knew rubbing amber generated static electricity‚ but they didn’t know why. The Greek word for amber is elektron. People knew about electricity for a long time. Ancient Greeks noticed that if they rubbed a piece of amber‚ feathers would
