    Abstract-“An electromagnetic brake is a new and revolutionary concept. Electromagnetic braking system is a modern technology braking system used in light motor vehicles like car, jeep, etc. This system is a combination of electro-mechanical concepts. An electromagnetic braking system uses magnetic force to engage the brake, but the power required for braking is transmitted manually. The disc is connected to a shaft and the electromagnet is mounted on the frame .When electricity is applied to the

    sky at night is possible because of the emission and reflection of light. 'Light' is the better-known term for the electromagnetic spectrum, which includes waves in the visible, ultra-violet, infra-red, microwave, radio, X-ray and gamma-ray regions. The scale of the spectrum is so large that no region is distinct, several overlap each other. Each of these regions in the electromagnetic spectrum represent transverse waves, travelling as electrical and magnetic fields which interact perpendicularly

    Frequency) generator. It generates frequency’s directly above the AM band and below the VHF (Very High Frequency) or TV band. It will zap the Ionosphere which is between 40 and 600 miles above the earth’s surface. The ionosphere helps to shield out electromagnetic waves from space that are harmful to life on earth. There are other ionospheric heaters located throughout the world. This specific one differs though from the others in that it concentrates all the energy on one specific spot. This cause a

    both microwaves and longer radio waves. These are transmitted in two ways: amplitude modulation (AM ) and frequency modulation ( FM ). These two kinds of wave have many differences. Radio waves are among the many types of electromagnetic waves that travel within the electromagnetic spectrum. Radio waves can be defined by their frequency (in hertz, after Heinich Hertz , who first produced radio waves electronically), which is number of times they pass through a complete cycle per second; or by their

    X-ray Diffraction X rays can be defined as “electromagnetic waves of short wavelength, capable of penetrating some thickness of matter.” Approximately the same size as an atom, the wavelength of an X-ray is about 1 Å (10-10m). They occur in the portion of the electromagnetic spectrum between gamma rays and ultra violet light and have proved very useful in determining crystal structures since their discovery on November 8th, 1895. German scientist Wilhelm Roentgen was conducting experiments

    conducting this experiment is to acquire the effects formed when diffractive grating takes place using a double slit diffraction disk and to find the wavelength of light, which is the purpose of diffractive grating. Theory ------ When electromagnetic waves are diffracted by diffractive slits, interference occurs. The pockets of light (photons) are dispersed into different directions. These are what we call spectral orders The formula derived for diffractive grating is d sin q=nλ

    Mathematical modeling: The electromagnetic levitation system includes an electromagnet, a permanent levitating magnet and a Hall effect sensor. The system’s model is shown in Figure 1, where 'R' is the resistance of the coil, 'L' is the inductance of the coil, 'v' is the voltage across the electromagnet, 'i' is the current through the electromagnet, 'm' is the mass of the levitating magnet, 'g’ is the gravitational acceleration, d is the distance from the top of the electromagnet to the levitating

    One of these important fundamental qualities is the fact that visible light is electromagnetic radiation. Electromagnetic Radiation, Photons, and Energy Levels Electromagnetic radiation has many different classifications. Some such classifications include AM/FM Radio Waves, microwaves, visible light, x-rays, and gamma rays. A key factor in these classifications is that each different type or "level" of electromagnetic radiation contains different energy levels. These energy levels are determined

    Telescope Light and other kinds of electromagnetic radiation coming from the universe outside the Earth must travel enormous distances through space and time to reach observers. Only the brightest and nearest stars can be seen with the unaided eye. To see farther and to clarify and measure what is seen, a telescope is needed. The word telescope is derived from the Greek words tele, "from afar," and skopos, "viewer." Even a simple homemade telescope can clearly show Saturn's rings, Jupiter's bands
