Electricity with its versatile applications is being utilized to switch from conventional combustion vehicles to electric vehicles. The scenario of travelling is changing rapidly with metros, electric rails, electric aeroplanes (solar), etc. Basically it indicates that electrical energy is being used almost everywhere to drive our life. But the current machines we use today are low in efficiency. Hence we require products with more power but also with higher efficiency. Magnetism possesses a magnificent opening for development. Bullet trains using the technology of magnetic levitation have proved the strong nature of electromagnetic fields. Keeping in mind the arising needs of the industry, in this project we tried to design and experiment, a system called Magnetic Repulsion Piston Engine, which makes use of magnetic force to drive a load. The working principle is based on attraction and repulsion between a permanent magnet and an electromagnet. The forces thus developed are used to generate mechanical power. Successful development in this field can actively help switch over IC Engines. Keywords: Magnetic Engine, Repulsion and Attraction, Electromagnet, Permanent magnet, Relay, H – Bridge circuit. 1. Introduction IC Engine, one of the greatest inventions of mankind, is one of the most important elements in our life today. It’s most important application being in automobiles, trains, and aeroplanes. Our lifestyle today cannot exist without a way to commutate. IC engines make use of gasoline and diesel. The population is in the rising trend; this means more the number of individuals, more the requirement of automobiles to commute. Every year there are around 50 million automobiles being manufactured all over the world. This situation is very grim. With this rise in use of fossil fuels, there arises a need to switch to alternative sources of fuel, to drive our engines. But the challenge is to develop machines which have much higher efficiencies than what we make use today. The most versatile form of energy that is widely used is electricity. Electric motors are replacing existing IC engines rapidly. But the storage of electricity holds a drawback, as a large amount of energy cannot be stored. This demands our machines to possess higher efficiencies, consuming lesser energy and producing more output. With this rising need of switching to alternative fuels, and alternative sources of energy, magnetism shows a bright spot in the current scenario. Magnetism is a phenomenon which exists in our body, our earth as well as our universe. The virtual concept of black holes have been said to be related to strong magnetic fields. The tremendous energy within a black hole pulls matter inside it to nowhere. If magnetism can possess such potential, then tapping it the right way can create wonders. Various researches across the world have proved that magnetic power can be used to develop over- unity devices. Though practically it possesses a lot of limitations to gain efficiency over unity, achieving near around the same can change the scenario a lot. The development the magnetic repulsion piston engine refers to the system where the piston attached with a permanent magnet is being pushed by an electromagnet, and again being attracted. The reciprocating motion of the piston is converted into rotary motion by the con rod and crank. The uniqueness of the development is that Magnetic Repulsion Piston Engine can be incorporated in various machines performing various tasks. Not only in automobiles, but it can be used as the prime mover in locomotives, lawnmowers, golf cart as well. They can complement or replace existing internal combustion engines that use fossil fuels. This system is environmentally friendly, and does not pollute the ecosystem and its application tends limitless with working cost being minimal. With this we would like to bring forward the most important components of our system. The power generation system consists of the solenoid, permanent magnets, and a battery. The mechanical sub-system mainly consists of the slider crank mechanism. And the electronic control system comprises a sensor and switching circuit. 1.1 Permanent Magnet Magnetism is a phenomenon where a force arises between magnets and objects, creating a magnetic field around, which in turn may create a repulsive or attractive force. All materials experience magnetism, but at different intensities. Permanent magnets usually governed by ferromagnetism produces the strongest effects in a magnetic field. Others such as paramagnetic materials attract only certain materials, and diamagnetic materials are repelled by magnetic fields. Also recent developments show the existence of anti- ferromagnetism in a very complex manner. Magnetic fields are a mathematical representation to show how magnetic materials interact with electric currents. The fields indicate values of strength as well as in the directions they are acting. Magnets are dipoles in nature, i.e., one face possess a north pole, and the other south. The origin of magnetism sources to the motion of electrically charged particles which are exerted by a force called Lorentz force. Developments in quantum physics say that the attraction of magnets is due to exchange of photons between the two poles. Permanent magnet is an object made from material that is magnetized and creates its own persistent magnetic field. Main way the permanent magnet created is by heating Paper ID: NOV151877 338
