In order to understand the relationship between light, magnetism and electricity, it is necessary to understand electromagnetism force, since this is the basis upon which the relationship is embarked on. In this essence, it should be noted that it is impossible to have electricity, in the absence of magnetism. This is because electricity conduction is only achieved through magnetic transmission. Electricity, to start with, is the energy charge that is transmitted through the flow of electrons through a conducting agent from one point to the next. This is referred to as an electric current. One of the most essential things to note in this case, include the fact that electric charge can only be successfully conducted through the movement of electrons, through a conducting agent, from one point to the next (Ede & McCormac 285).
Magnetism and electricity
Magnetism and electricity are two entities that are dependent upon each other, and none can exist without its reliance upon the other, as it will be established here. Firstly, it is necessary to understand that there should be the existence of a magnetic field, as well as an electric current (static charge) and a linking conductor (such as a wire, for example), in order for there to be a relationship between magnetism and electricity. The magnetic field in this case, comprises of positively and negatively charged electrons (protons and neutrons, respectively). When static charge is introduced to the conductor containing the positively and negatively charged electrons, the electrons inversely attract each other, whereby, the positive electrons attract the negative electrons. With the alignment of the same, they create a static path for the static charge to pass through. Consequently, the charge is passed from one point to the next across the conductor, to its receiver. The conduction of static energy, which is in this case the electric charge, is not possible with the absence of magnetic conduction and attraction between the positively charged and the negatively charged electrons. From this analysis, therefore, it is evident that electricity and magnetism and related to each other, and are also dependent upon each other. This is because magnetism cannot take place or exist in the absence of electric charge, while electric conduction cannot exist in the absence of magnetism between the positive and negative electrons (Ede & McCormac 287).
Magnetism, electricity and light
As it has already been established above, magnetism and electricity and directly independent and can only take place if both of them are present. Bearing this in mind, therefore, it is necessary to note the fact that the conduction of light relies on both magnetism and electricity, in order for light waves to be projected from one point to the next. For example, the wavelength distance (the distance between two wave parts with the same electricity field strength) is one of the factors that determine the conduction of light from one point to the next, and this is directly dependent on the effective conduction of electrostatic charge between the two points (Ede & McCormac 284). As it has already been established, the conduction of the electric charge is dependent on effective conduction of electrons, through magnetism. Therefore, the only way through which light can be conducted is through magnetism, and the presence of a conductor that will support electromagnetic movement of charge through the positively and negatively charged electrons in the conductor (for example, a wire).
Scientist accredited to the principle
This relationship between light, magnetism and electricity was discovered by Hans Christian Ørsted (1777-1851), a Danish scientist majoring in chemistry and physics. He is the person accredited for discovering, explaining and developing the principle of electromagnetism. From his analysis and explanation, therefore, it is necessary to note the fact that all these aspects are also directly related to light, since light is generated from electric charge. There are various aspects that should be considered in order to understand the relationship between the three. For example, it is necessary for magnetic attraction between the protons and neutrons to take place when static charge is conducted through a conductive element, in order for light to be produced as the final product. At the same time, this conduction is only possible and achievable when two unlike elements (protons which are positively charged and neutrons which are negatively charged) attract each other through magnetic charge, in order to conduct energy through the conductor, for light to be produced as the final product.
