Name:David Toledo Room: 401 Review of Literature Target Audience 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

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

The alternating current induces a shifting magnetic field, which creates different temporary poles at timed intervals. Due to the positioning of the semiconducting magnets and creation of the different electromagnetic forces, the like pole tend to push while the unlike poles attract, therefore, causing motion in the direction dictated by the alternating current (Funk and Getsla, 2006). Adoption of this technology in

“Science in the Media” Project In the movie Back to the Future part II, Dock goes to Marty’s house and parks his flying car in Marty’s driveway. Just before they leave to head off into the future, Doc rummages through Marty’s trash. In there he finds waded up paper bags, a banana peel, and a partially filled beer can. Doc then inserts the trash that he finds into the top of the engine component of his flying car. Immediately after doing so, they hover off into the future. This particular scene in

The findings of Lu et al (2013) study suggest that it consists of primary coils, secondary coils and levitation magnet. As Lu et al (2013) state, the train is driven by the interaction between traveling magnetic field and the eddy currents, as well as thrust force. This can be demonstrated by the electricity magnetism. However, the limitations of this system can be

discoveries, observations and inventions have been made relating to the topic at hand. There is history behind who studied it first, there are car motors that have in depth studies about the effects of temperature on magnetism, there are nanostructured magnets, there have been new discoveries made in the last decade about the topic, and there are also many present-day applications to the topic. In 1911, superconductivity was first studied by Heike Kamerlingh Onnes, a Dutch physicist. He studied this by

In the world of today complex medical emergencies are becoming more and more common. Physics plays a major role in the technology that we use to accurately diagnose these medical cases in a time effective manner. Many different physics concepts are involved in the MRI and CT scanning process and without proper understanding of these concepts and how they works it would not be possible to have the medical equipment that is available today. These concepts include beam hardening and dual-energy, filtered

INTRODUCTION The world today is entirely dependent on various means of transportation for their day to day and hence a more rapid and reliable source of transportation is must. People today recognizes aero plane as the fastest means of transportation which has its own disadvantages and there were no other options available till the beginning of the 20th century , but with the development in technology there were other means of transport which came into action and one of which was the MAGLEV TRAIN

3. DATA AND METHODOLOGY 3.1. Magnetic Data The used data are based on the reduced to pole (RTP) aeromagnetic data (Fig. 2) with contour interval of 20 nT, scale 1:250,000 (total field of the area is 41,400 nT, inclination angle is 37.4 degrees and declination angle is +1.6 degrees). The magnetic data was compiled for the Eastern Desert and the Red Sea, based on Meshref (1990) and available in Saad (1991). The Union Oil Company carried out this survey in 1974. Fig. (2): 3.2. Determination of the
