Theories of Electricity and Magnetism - Essay Example It is possible to transform an electric field into a magnetic field and vice versa. This essay will therefore analyze the properties of electricity and magnetism and their relationship with respective theories. Magnetism There are three basic properties of magnetism. These properties are the basic behaviors of magnets and they define laws that govern magnetism. The first property of magnetism is the bipolar property. According to this property, a magnet has two unlike poles. It is also impossible to separate the two poles of a magnet or to create a monopole magnet. This indicates that whenever a magnet is split into two pieces, two unlike poles always result creating two independent and complete magnets. The second property of magnetism is the attraction of unlike poles and repulsion of like poles. This significant property forms the basis of most theories that governs magnetism. The third property of magnetism is the existence of a magnetic field or the region around the magnet with in which the effects of a magnet are experienced (David 109). A magnet has a strong field around its poles and its strength varies inversely with the distance from the magnet. Theories of magnetism are based on the three properties and they explain why magnets behave the way they do. Magnetic theories are also used to predict occurrences that cannot be verified physically as the three properties. The first significant theory of magnetism is the Weber’s theory of magnetism. According to this theory, the magnetic property of a magnet is based on the magnetic property of each individual molecule. Weber hypothesized that each molecule behaves like a tiny magnet that has the bipolar property discussed above. According to Weber’s theory, the difference between a magnet and non-magnet results from the magnetic field of each molecular magnet. During the magnetization process, the molecules of a piece of material are aligned in one direction with all their south poles and north poles facing in a similar direction. In an un-magnetized material opposite poles of each individual molecule are oriented in a similar direction resulting in cancellation of the magnetic force. Such a material will have zero resultant force (David 119). This theory is closely related to the bipolar property of a magnet. According to the theory, the two poles of each magnet results from the fundamental molecular magnet that forms the magnet under consideration. The inability to create a monopole magnet also has its basis on the existence of bipolar molecules. Each split or separation of a magnet results into two independent magnets with independent south poles and north poles. This is because the splitting of a magnet does not affect the direction of the magnetic force of each individual molar magnet. Finally, the theory supports the field property of magnets. This is because the magnetic field around each magnet results from the cumulative field of each individual molecule. The sec ond significant theory of magnetism is the domain theory. This theory is based on the orbiting or spinning of electrons around the nucleus. The spinning of electrons creates both an electric and magnetic field around the electron. When most of the electrons within an atom spin in a similar direction, a magnetic field results around the atom. Magnetism results from the resultant effects of such electrons. On the other hand, the atoms of a non-magnetized mater

Marketing Managment - Essay Example This paper approves that organizations buying behavior is dissimilar to the consumers. Organizations are affected by environmental, organizational, interpersonal and individual factors. These individuals have their own set of behaviors and tend to influence others through interpersonal contact. In the environmental factors side, economic conditions is considered, the state of technological change is monitored, political and social factors are kept in mind and competitive developments play a major role in the company’s decision. At present, green marketing/ environment marketing has no strategies for the conventional process of segmenting, targeting and positioning. This is due to the fact that green marketing is a relatively new phenomenon with not set rules therefore the process is constantly updated, shifted, revised and new rules are created. One can use the traditional way marketing works with segmentation, targeting and position and merge newer reforms into this. This essay makes a conclusion that research conducted in the field of environment marketing, needs to be extensive and experimental. Organizations that declared their own selves to be socially responsible should understand the transitional phase green marketing in undergoing. Universities etc need to implement details about green marketing into their curriculum. Countries that are remote need to be made aware of their natural resource and taught the proper implementations of these. Above all green market is a profitable theory which needs to be realized by governments of other countries. Organizations such as The Body Shop have shown to their competitors that ozone-friendly products are in demand and appreciated by the public. However the publics of developing countries do not have this option and must be given so.
