Studies on electromagnetic engine

Over the last century numerous changes were brought to the internal combustion engines. Numerous researches are carried out in hopes of improving the engine characteristics. Increasing the efficiency and reducing the exhaust gases have been the dominant in the fields of research. The volume and number of applications of engines have grown steadily, penetrating and conquering new markets relentlessly. The exhaust gases contain numerous pollutants that are extremely harmful though in chronic conditions. Hence, Electromagnetic engines were created that uses the combined power of an electromagnet as well as a permanent magnet. These engines cause no air pollution and are a dominant force when this world faces huge crisis due to inadequate fossil fuels. While these engines have already proven their worth as alternative sourced engines, non-polluting and eco-friendly, the current challenge is to make them more efficient and cost effective. This review paper discuss about worldwide review report on the various configurations and their results. Also, this paper concentrates on magnetic damping properties, residual magnetism and the effect of heat on neodymium magnets. A prototype is designed where relay switches are replaced with position sensors. The key reason behind this study is to provide a clear idea of the current existing methods in configuring an electromagnetic engine and to state the existing problems that exist in constructing these engines.
