system that allows each vehicle to warp around a T-shape guide way. Electrodynamics systems are systems that utilize magnetic repulsion rather than attraction. The similarities between these two Mag-lev vehicle systems are that they both utilize magnets. However the difference between them is that one looses all their resistance and other still has it. Although the similarities between these two systems is that they have major problems that are affecting the systems‚ for example the EMS requires

physical concepts used in a Magnetic Resonance Imaging‚ also known as MRI‚ machine. There are many physical concepts used when an MRI is taken of the body‚ such as; radio waves‚ resonance and pulse sequences‚ magnetic fields being produced and lastly‚ magnets. Radio waves much stronger than the magnetic field of the Earth are sent through the body which causes the nuclei in the body to move to a different position. When the nuclei move back to the place they originated from‚ they send back radio waves

diaphragm vibrates back and forth‚ and the attached coil moves along with it. Additionally‚ magnet is attached with coils on a cardboard. When the coil alternately approaches and move back from the magnet‚ the flux through the coil changes. As a result of this‚ an ac emf is induced in the coil. Next‚ this electrical signal is sent to an amplifier and to the speakers respectively. In a moving-magnet microphone‚ the magnet is attached to the diaphragm and moves relative to a stationary coil. The handmade

transportation. Perhaps‚ in the future‚ electricity could be less expensive and more efficient by developing new methods of production‚ such as the use of nuclear energy to generate electricity. Indeed‚ electromagnetism proves that electricity and magnets are not merely for having lights and air conditioning‚ or even sticking notes to the refrigerator. Electromagnetism is an essential concept behind most of today’s modern

the U-magnets? The distribution of magnetic flux lines when the iron ring is placed in between the magnets‚ the iron ring is included in the distribution of flux lines. Instead of connecting to the other pole‚ the ring affects its distribution and some of it is attracted to the iron ring. 2. How does changing the current affect the magnetic force on a wire suspended in a magnetic field? As the current rises‚ the magnetic force is pushing the magnet away from the current‚ or pulls the magnet either

.INTRODUCTION Magnetic levitation is the latest in transportation technology and has been the interest of many countries around the world. The idea has been around since 1904 when Robert Goddard‚ an American Rocket scientist‚ created a theory that trains could be lifted off the tracks by the use of electromagnetic rails. Many assumptions and ideas were brought about throughout the following years‚ but it was not until the 1970’s that Japan and Germany showed interest in
