Science Fair Proposal Edward Montanez Everman Joe C.Bean High School Abstract A hydroelectric generator is a machine that uses mechanical energy to generate electricity, the hydroelectricity comes from a large volumes of falling water to create the mechanical energy. I will be constructing my own hydroelectric generator in order to show it is possible to create electricity using large volumes of water, enough power to light a light bulb.

There is not much that can be done without the use of magnets. The obvious uses are in hospitals with MRI machines, in our car and mobile phone speakers so we can hear our calls and enjoy our music. However, the use of magnets in nearly all electronics is often overlooked. Electronics need magnets to run, whether it’s a vacuum cleaner, the windows in a car, or the office telephone. Although men lived and worked at one time without magnets, it is impossible today. Living, working and relaxing

The Magnetic Organizer will appeal to a young-older audience. Both boys and girls can be unorganized, and therefore the Magnetic Organizer is for both genders. The Magnetic Organizer can appeal to many students who have trouble being organized in school. Leaving folders, papers, or homework somewhere are constant struggles of students. Magnetic Organizers can be used by both amateurs and professionals as both need to be organized in order to either become a professional, or stay one. The disabled

MRI, or Magnetic Resonance Imaging is a technique using magnetic waves and radio-waves to investigate the human anatomy and physiology. The usage of the magnetic waves protects patients from other harmful effects present in other forms of scans, such as the ionising radiation in CT scans. The process of how an MRI operates is complicated, and involves many principles of Physics, by using the water molecules within the human body to construct a complex, three-dimensional view of the anatomy . The

mentioned criteria. I have only one way that will allow me to live the successful life I dream of, and that’s my education. I worked my hardest during elementary school just so I could be able to attend one of the top high schools in Chicago and only then was I accepted into Whitney M. Young Magnet High School, one of the top three high schools in the state. At Whitney Young, I participate in many clubs and extracurricular activities, including cheerleading, student council, Chicago Student Union

Magnet - creates a magnetic field. The stronger it is the higher efficiency and accuracy of a speaker. It is worth noting that nowadays this is a permanent magnet as opposed to the earliest designs which used electromagnets. The most common and cheapest material used is ferrite but the most effective are alnico magnets (consist of aluminium–nickel–cobalt hence the name). Field gap – should be as small as

magnetic field. The magnet will only move if the magnetic field is strong enough. The wire carrying the electrical current behaves like a magnet. It either attracts or repels the magnet that is above it. If the direction of the magnetic field changes, then the direction of the electrical current changes. Magnetic field is formed in concentric circles around a current-carrying wire, laying the wire flat ensures that the strongest part of the wire’s magnetic field interacts with the magnet. Electricity and

the entire system, such as the arrangement of the indexes in the Stock Market. Main Engine Console. This component is the basically the ‘body’ of the entire Robotic Arm Connector Module and it specifically contains many areas of gears, gear belts, magnets, computer chips, and stepping motors. When an astronaut sends information from the computer to the robotic arm, the wires will transport the electrons to the microchip where the information will be deciphered by its internal program. Afterwards, the

used for navigation in the 11th-12th century, only arriving in Europe towards the end of this period. Then, in 1600, William Gilbert (Figure 1.1) published De Magnete, Magnetisque Corporibus, et de Magno Magnete Tellue (On the Magnet and Magnetic Bodies, and on the Great Magnet the Earth). He concluded that the Earth itself was magnetic with a centre of iron, and this is why a compass would point north. Figure 1.1 William Gilbert (1544-1603) , author of De Magnete, the first printed book written

change of magnetic flux through a circuit. Faraday’s experiment: Connect a coil of many turns to a zero centered galvanometer. Move a small magnet in and out of the coil and we can observe a small current is produced when the magnet is moved but no current when there was no movement. By varying the speed (relative motion) of the movement and strength of magnet, the galvanometer flickered more therefore more current produced. Distance also affects this. 2.2.2 Magnetic field strength and magnetic
