This document describes a project to design an electromagnetic suspension system that can convert the linear motion of vehicle shock absorbers into electricity. The system would utilize a metal shaft, spring, magnets, copper coils, and frame to generate a voltage between 125mV to 350mV as the suspension moves. This captured energy could then be stored in a battery to power small electrical systems in the vehicle. The document outlines the components, diagrams, working methodology, advantages, and project plan for developing this system to extract useful energy from the vehicle's suspension.

2. Abstract
The power generator electromagnetic suspension system is a system that
converts vehicle bump generated linear motion & vibration, into electricity to
be used in battery charging. General vehicle shock absorbers are used to simply
absorb this energy without converting it to electricity. So here we put forth a
way to use this free energy and store it for further needs such as vehicle lights,
cooling, indicator lights etc. With the concept, the derivation of specifications and
the process of designing the Suspension System is delineated. The Suspension System
generated a potential difference in the range of 125 mV to 350 mV.

3. Introduction
This we here use the principles of electromagnetism in order to generate
electricity from this motion. Our shock absorber is made up of a metal shaft,
spring, magnet, coils, base with screws and joints. It uses a coil wound around
in particular turning arrangement over the inner beam of the part. We use
cylindrical supports in order to minimize friction and ensure smooth generation.
The head of the absorber consists of magnets attached to outer core which are
aligned with inner core to ensure smooth motion while ensuring efficient
generation.

4. Project Justification
This arrangement is fitted with springs in a precise manner so as to achieve the
desired motion and magnet coil overlapping which allows for generation of
electricity through electromagnetism principle. Thus our system puts forward a
smart power generation system using electromagnetic suspension system. From
the literature survey it was understand that there is a lot of energy wasted from the
suspension. Only around 24% of the energy from the combustion of the fuel is used for
motion of the vehicle and to run various systems. Suspension system possesses high
potential for regeneration of electricity as the reciprocation of springs is constantly
occurring as around 200 W of energy is lost through the dampers.
