Abstract— when a vehicle moves on the road it encounters many bumps and uneven terrain which results in vertical motion which is often considered undesirable and compensated with a suspension system. A suspension is a system of springs and dampers which allows relative motion between the wheels and the chassis thus neutralising the effect of the vertical force. This motion of the spring is solely used to oppose the vertical force and other possibilities are neglected. Based on Faradays law of EMI “when the magnetic flux linked with a circuit changes an EMF is induced”, a system can be incorporated in the suspension system to make use of the vertical motion of the spring, which if subjected to a magnetic flux will experience a continuous change of field due to the vertical motion and thus generate electricity. The current generated is proportional to the magnetic field and can be enhanced by arranging the dipoles of the magnet and cross doping of varieties of magnets.
