MAGNETIC LEVITATION AND TRAINS BY: MANISH KUMAR 2K12/EE/075 Delhi Technological University INTRODUCTION MAGLEV = MAGNETIC + LEVITATION Magnetic means “based on magnets” Levitation means “to rise and float in air” Maglev is a method of propulsion that uses magnetic levitation to propel vehicles with magnets rather than with wheels that the conventional trains use. Magnetic levitation is the use of magnetic fields to levitate a (usually) metallic object. Manipulating magnetic fields and

IMPORTANT QUESTIONS IN PHYSICS (CLASS XII) ELECTROSTATICS One mark questions. 1. If a point charge is rotated in a circle of radius r around a charge q‚ what will be the be the work done? 2. Does the electric potential increase or decrease along the electric line of force? 3. Give the relation between electric intensity and electric flux. 4. What is the dielectric constant of a metal? 5. What is the potential energy of two equal negative point charges 2μC each held 1m apart in air?

Body modification is the deliberate alerting of the human anatomy or the human physical appearance. What drives people to radically reshape their bodies or go under the knife to seek physical perfection? Or to stretch human bones like the Kayan women in Nai Soi Thailand. Tattoos‚ piercings‚ implants‚ hair color: As a species were either trying to stand out or fit in. The changes we make to our bodies do not just define us; they define the very culture we live in. On the remote border of the Thailand

Environment Temperature Control Using Modbus and RS485 Communication Standards Abstract – This paper reports an undergraduate engineering team’s effort to develop a system which emulates a curing process chamber found in many industry settings. Based on industry utilization of bus protocols‚ it has been determined that the de facto standard Modbus protocol under the industry recommended standard interface RS485 is an appropriate communication method for this closed-loop control system.

the top cylinder there is clip attached. The clip is used so one could clip it too‚ for example‚ the inside of the pocket of a shirt. 2) Spring/Coil: The Pilot EasyTouch pen works because of the 2cm long spring. The spring’s diameter is just slightly bigger than the ballpoint’s body. Wide enough to lightly hug the cylinder shaped ballpoint body. The coil creates the tension necessary for the ballpoint of the pen to stay out. Clicking the end of pen when the ballpoint pen is out releases the tension

experience‚ we decided on using Helmholtz coils to produce a reasonably uniform magnetic field. We measured the deflection of an electron‚ (our dependent‚ “response”‚ variable)‚ as a function of the magnitude of the magnetic field‚ ‚ and the electron’s velocity‚ (our independent‚ “control”‚ variables). Prediction and Procedure For this experiment‚ we used the CRT‚ a digital multimeter (DMM)‚ compass‚ meter stick‚ 200-turn (each) Helmholtz coils‚ a Hall probe to measure the magnetic field
