Magnets are used in all types of electrical applications and without magnets the technology that people take for granted would not be possible. “Magnets are essential for the generation of electric power and are used in motors, generators …” (Magnet). However, understanding magnets at the atomic level will give the source to why magnets have a south and north pole. The electrons of an atom are similar in all atoms for they spin or rotate as they move around ... ... middle of paper ... ...ield, sending a shock wave of magnetic energy down to the surface, creating a way to harness electricity from the planet. Taking into consideration that in theory electricity can come from the magnetic field around Earth, no devices have been developed to show that this device actually works in this day and time.
The magnetic field itself is invisible, but the magnetic field strength can be measured through the use of special equipment. The magnetic field weakens the further you move away from the wire and will always be perpendicular to the wire and the fields direction depends on the which direction the current if flowing. Since the magnetic field is always circular and perpendicular to the wire, the magnetic field can be increased simply by creating a coil of wire. Figure 3 shows an example of a simple electromagnet by coiling a wire around a nail and connecting it to a power source. The magnetic field is amplified by each loop of wire around the nail.
Because of western world energy codes and technologies, the methods of storing/disposing of nuclear waste are safer than ever. In addition to an increased focus on saving the environment, many governments have proclaimed a need for energy through a method that is environmentally friendly. According to the World Nuclear Association, “Electricity demand is increasing twice as fast as overall energy use and is likely to rise by more than two-thirds 2011 to 2035 (World Energy Needs and Nuclear Power)”. As of now, Nuclear power provides about 11% of the world's electricity (Ricotti). Only through nuclear energy will the world’s exponential energy demands be met.
Nuclear Energy: The Future Energy Source America uses a lot of energy to supply electricity to millions of homes and businesses and needs an energy source that will supply an abundant amount of power but is also efficient. Nuclear energy is a reliable and efficient energy source that America can use. Fossil fuels and other resources used in the United States are running out or are very expensive. Nuclear power will provide a cost effective and long term power supply. America should use nuclear energy because of its many benefits which are environmental benefits, economic benefits, safety, power production, and reliability.. Nuclear power is a potential energy source for America because of its many economic benefits.
The most important part of magnetism to make electric motors work is: A magnet has two different ends, or poles a north and a south pole. These poles behave like electric charges, like poles repel and unlike poles attract although magnets have no affect on still charges. The relationship between electricity and magnetism is that each phenomenon is that each generates a field. Electric fields can be pictured by thinking in terms of gravitational forces. Where, any two objects have a gravitational force one another.
Introduction: The design of simple electric generator is performed to testify three important physics concepts by three hypothesizes. Based on the transformation and conservation of energy,knowing that the total energy of an isolated system cannot change, but can be transformed from other forms. The first hypothesize is spinning the nail can lighten the bulb which can testify the basic idea of electromagnetic Induction.The second hypothesize is the number of the coils which are winded on the device is deciding factor of whether the bulb is lightened or not. This is the application of solenoid that the strength of magnetic field produced by a current is directly proportional to the number of turns in the solenoid. The third hypothesize the little bulb will be lightened after spinning the magnet at a certain speed.
The purpose of this paper is to talk about magnetic monopoles, their history, synthetic monopoles, and their applications. Although natural monopoles have yet to be discovered and we are still testing the development of synthetic monopoles that are far from perfect, monopoles, with their unique properties would bring dramatic changes to our society and would rapidly move up to the next level of technology. Hypothetically speaking, monopoles could be used to create a magnetic train similar to maglevs, and a unique motor/generator. What Are Monopoles? All magnets in nature are dipoles, that is, magnets having both a north and south pole (Gibney).
Nuclear energy now is the world’s mainly useful form of energy. Energy are devolved and have been used from the fossils fuels and are still be used now, but it is not an option to use it in the future. So this turned that we have a nuclear power as the best choice. There are many positives to nuclear energy over fossil fuels such as less global warming effects. At this time nuclear power provides 6% of the world’s energy and about 14% of the world’s electricity.
Nanotechnologies will help reduce weight of carbon emission in transportation utilizing nanocomposite materials that quickly diffuses across the automotive and aerospace industries. Applications of nanotechnologies will result in a global annual savings of 8000 tons of carbon dioxide, which will rise even further to over millions tons by 2020. But, let’s focus on the positive effects of Green Nanotechnology in Solar. Although Solar Energy is a flexible source of where energy could be directly or indirectly converted into forms of energy, it’s still not perfect. With its inefficiency, scientists are trying to find alternative solution to store solar cells for as long as possible.
Room temperature superconductivity would totally revolutionize the electrical power industry by making copper wires obsolete. Superconductivity would also improve transportation by changing the way trains, cars, and ships run. Magnetically levitated trains have the advantages of speed and quiet operation and the same magnetic levitation could be used with cars. Drivers would travel as fast as 150 mph on a highway and they would never have to worry about collisions. Ships propelled by superconducting motors would weigh less and would be more maneuverable.
