Energy, Electricity and Concepts

Josué Ortiz Santos

Magnetic and electric fields are interesting concepts found on the earth. It has been very helpful in our world for years. Thanks to it we can use right now our computers and communication items expanding our knowledge. The interplay between these two things is one of the reasons that magnetic and electric fields are used for many things from powering motors to recording sound and information. Electromagnetism is also widely used in a hospital’s equipment and is vital for the survival of many people every day. Electromagnetism is essential for many functions of our everyday and industries; it is now hard to think what life would be like without these forces. Like this type of energy has been useful to our world another type of energy like photoelectric or other one could be created and useful for many applications. 

Ideas of electromagnetism electricity start from simple objects such as springs, coils and magnets that simply created a current. Now these theories have expanded to a point where our everyday lives are affected by it. People start their cars for example; a magnet turned by a flywheel generates current through coils to help ignite the cars electrical system. There are many examples of electromagnetism effecting technical objects of today. One particular example would be radar devices used for tracking ships, cars, or even submarines. The ideas of sending out a signal composed of a wave of certain frequency and wavelength returned at a certain time can be used to find objects or map out underwater territory, example the policemen radar speeds of drive-by cars. This is just a fraction of the uses of electromagnetism. 

The photoelectric effect is the phenomenon where by electrons are emitted from a surface, usually metallic upon the exposure to and absorption of electromagnetic radiation, such as visible light, that is above the threshold frequency. The light is giving its energy to electrons in the atoms of the metal and allowing them to move around, producing the current. This is because electrons cannot get enough energy to overcome their atomic bonding. The photoelectric effect furthered wave particle duality, whereby physical systems can display both waves and particle properties and behaviors, a concept used by the creators of quantum mechanics. Einstein wasn't the first person to use the idea of photons, but he was the first to make it the starting point of an explanation rather than a convenient fiddle to explain away odd results. Things like solar energy use this effect to produce energy. This is a useful energy because we got it from the light of sun without the use of petroleum or other things that can affect our environment and very effective.

Electromagnetism has many applications right now. I think that this concept combined with electromagnetic waves will be the new era in the next years. Many people are looking new kind of energies and this is one of them. If we make the photoelectric success we also can get energy from it. The flow of electrons make we generate energy so if we use this process maybe we can generate energy in other way. Petroleum is an old way of generating energy, new ones like the ones discussed will be the new era. Researching many aspects we can find others effective process to do things without affect or planet. With physics we can understand and discover old and new phenomenon.
