attraction is used‚ it is known as magnetic suspension. If magnetic repulsion is used‚ it is known as magnetic levitation. In the past‚ magnetic levitation was attempted by using permanent magnets. Earnshaw’s theorem however‚ proves that this is mathematically impossible. There exists no arrangement of static magnets of charges that can stably levitate an object. There are however means of circumventing this theorem by altering its basic assumptions. The following conditions are exceptions to Earnshaw’s

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

Far West is a community striving to provide the perfect community and educational atmosphere for those that look to call Far West home. A program that is focusing on producing a successful program for a diverse population would have to utilize some program planning. This is especially accurate when a majority of the school population is of an Asian descent. Not only will program planning need to take place

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

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.

Stakeholders can be defined as all entities that are impacted through a business running its operations and conducting other activities related to its existence. The impact can be direct in the case of the business’s customers and suppliers or indirect in the case of the communities in which the business chooses to place its locations. Businesses must consider the needs and expectations of its stakeholders‚ though it need not consider them to be of equal importance. Certain stakeholders such as owners

CheckPoint: Functionality of Programs When a program starts in an object-oriented language‚ information is put into compartments. This is what allows the program to compute things. In this example‚ we’ll be taking an e-business and examining an order has been placed within said program. All of the data is put into the right compartments‚ but what happens when the order needs to be submitted? The program has to have the capability of taking the data from the compartments and saving it to a file that
