Abstract
Majority of braking system work on the principle of dissipation of kinetic energy to heat energy.This method has its own drawbacks and must be replaced with more reliable braking system that is quick in response,doesnt heat and also maintanenece free.In this project,a frictionless braking system is proposed using eddy current phenomenon.This phenomenon is governed by faradays law of electromagnetic induction and Lenz law.Eddy cureent is created by the relative motion between a magnet and a metal(or alloy) conductor.The current induces magnetic fieldsin the conductor which opposes the actual magnetic field of the magnet and results in the decceleration of motion (Lenz law).The constant magnetic field is the simplest and easiest design to implement.The mechanism implements this phenomenon in developing a braking system.This braking system is frictionless,hence its advantageous over conventional friction brakes in terms of performance and maintanence.The proposed system is implemented in rear wheel of vehicles
