SYNOPSIS ON ELECTROMAGNETIC ELECTROMAGNET IC CAR INTRODUCTION:
Electromagnetic energy is a limitless limitles s source of power that is used in many industries across the United States. This technology runs several key instruments in modern automobiles, from electrical features, to whole ignition systems and engines. For countries looking for energy independence, electromagnetic propulsion systems in automobiles provide an alternative to fossil fuels by simply plugging the vehicle into an outlet at t he end of the day. In this project we are designing an electromagnetic car, which will use electromagnetic piston engine. Electric cars are the future. They have several potential benefits when compared to conventional internal combustion automobiles. The Electric Engine
An electric motor is built on coils of wire which are driven through the magnetic force created by electromagnets. Electrical force is converted into mechanical energy by the electromagnets which turn wheels and generate speed. Modern hybrid electric vehicles maintain this magnetic field through "regenerative braking" which allows resis tance (friction) created through wheel motion to reclaim the spent electrical forces needed to propel the vehicle along the road. WORKING PRINCIPLE:
The electromagnetic piston engine according to the present invention in one aspect comprises a cylinder and a piston, each made of a magnetic material, a cylinder electromagnet having an inner wall of the cylinder magnetisable to a one magnetic pole, and a piston magnetization unit for magnetizing a portion of the piston engage able with the cylinder to a single magnetic m agnetic pole in a fixed manner, in which the piston is transferred in a one direction by creating a magnetic attraction force between the cylinder and the piston by exciting the cylinder electromagnet; and the piston is then transferred in the opposite direction by creating a magnetic repellent force there between, followed by repeating this series of the actions of alternately creating the magnetic attraction force and the magnetic repellent force to allow the piston to perform a reciprocal movement. The electromagnetic piston engine according to the present invention in a still further aspect is constructed by arranging a combination of the cylinder with the piston in -the aspects described above as a one assembly, arranging the one assembly in plural numbers and operating the plural assemblies in a parallel way, and converting a reciprocal movement of the piston in each of the plural assemblies into a rotary movement of a single crank shaft by a crank mechanism so that more can be produce for propelling any heavy vehicle.
VEHICLE HARDWARE:
Several components found under the hood of an automobile are powered by electromagnets. A solenoid is a coil of wire that uses an electromagnet to create linear motion to bring mechanical pieces into line and close a circuit. This component is integral to the ignition process of modern automobiles. Other car parts, such as audio speakers, use electromagnets surrounded by a permanent magnet to create electrical impulses from sound waves. Magnets as Workers
Magnetic components have an advantage over non-magnetic equipment designed to perform similar functions, in that magnetic components require no contact with the object in order to work. They produce a force and continue to function through walls, pipes and conveyor belts, among others. This simple fact makes the Magnetic Resonance Imaging (MRI) machine, a medical breakthrough in diagnosing damage to the human body, possible. Life of the Magnet
Electromagnets also have constant strength over their lifetime, and have a much longer lifespan than non-magnetic equipment. Magnetic machine systems, for example, lose 0.5 % of their strength for every 100 years of operating life i n ideal conditions. Electromagnets may also withstand operational temperatures of up to 600 degrees Centigrade without losing power or functionality. Controllable Power
Power is able to be controlled in a much more deft way than with other magnets, in that an electromagnet is not just a simple "on and off" piece of equipment, but has a greater breadth of strength. An electromagnet may also be "turned off," whereas other magnetic machines are simply "on" all the time. ELECTROMAGNETS:
An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The magnetic field disappears when the current is turned off. Electromagnets are widely used as components of other electr ical devices, such as motors, generators, relays, loudspeakers, hard disks, MRI machines, scientific instruments, and magnetic separation equipment, as well as bei ng employed as industrial lifting electromagnets for picking up and moving heavy iron objects like scrap iron.
A simple electromagnet consisting of a coil of insulated wire wrapped around an iron core. The strength of magnetic field generated is proportional to the amount of current.
Current (I) through a wire produces a magnetic field ( B). The field is oriented according to the right-hand rule. An electric current flowing in a wire creates a magnetic field around the wire (see drawing below). To concentrate the magnetic field, in an electromagnet the wire is wound into a coil with many turns of wire lying side by side. The magnetic field of all the turns of wire passes through the center of the coil, creating a strong magnetic field there. A coil forming the shape of a straight tube (a helix) is called a solenoid; a solenoid that is bent into a donut shape so that the ends meet is called a toroid. Much stronger magnetic fields can be produced if a "core" of ferromagnetic material, such as soft iron, is placed inside the coil. The ferromagnetic core increases the magnetic field to thousands of times the strength of the field of the coil alone, due to the high magnetic permeability μ of the ferromagnetic material. This is called a ferromagnetic-core or iron-core electromagnet.

ADVANTAGES OF ELECTROMAGNETS:
The electromagnet has led to inventions and breakthroughs in energy and medicine that are far-reaching and far from fully realized. Its power is limited only by the human imagination, with implications as a renewable source of power for vehicle propulsion and imaging technology. How we use this technology going forward may be the key to energy independence and perhaps longer life.
