Recommended: Reflection about the history of electricity
It is the reason for the great technological movement of the 21st century. Its applications are used on a day-to-day basis. What is this form of energy? It is electricity. Electricity is defined as a form of energy from the existence of charged particles. The charged particles are either positive or negative (protons or electrons). Moreover, through the same principal, the phenomenon of magnetism is also applied on a day-to-day basis. Magnetism is defined as either an attractive or repulsive force between objects due to an electric charge. To thoroughly understand the strength of electricity and magnets, it is vital to first be cognizant of where and when they were discovered. The history of electricity is quite astonishing. Because electricity …show more content…
Figure 1 illustrates the design of the batteries discovered in ancient Persia. Fast forwarding to the 17th century, it was “in the year 1600, English Physician William Gilbert used the Latin word “electricus” to describe the force that certain substances exert when rubbed against each other” (Atkinson, 2014). Though Benjamin Franklin is largely accredited with the discovery of electricity, it was “Italian physicist Alessandro Volta [whom] discovered that particular chemical reactions could produce electricity” (Atkinson, 2014). In “1800, he constructed an early electric battery that produced a steady current” (Atinkson, 2014). To clarify, current is defined as the “rate at which charge flows through its surface” (Serway and Vuille, 2011). Volta ‘s battery was only the beginning. Michael Faraday made electricity more accessible when he “created the electric dynamo (a crude power generator)” (Atinkson, 2014). This invention “solved the problem of generating electric current in an ongoing and practical way” (Atinkson, 2014). Faraday’s solution helped Thomas Edison invent his famous light bulb because it was the “first practical bulb that would light for hours on end” (Atinkson, 2014). Edison is …show more content…
To explain what exactly Tesla and Edison did, it is important to know that in a DC system, electrons flow only in one direction. Where as in an AC system, the electric current reverses its direction many times during the time frame. To conclude, the use of electricity came from no one person, but actually a combination of quite a few intellectuals. Nonetheless, the reality of how electricity behaves is just as important as its history. Though there is still much to know about the nature of electricity, there is a basic understanding of its essence. As mentioned previously, electricity is a form of energy from the existence of charged particles. To thoroughly understand electricity, it is imperative to first analyze electric force. Coulomb’s law summarizes the electric force between two objects. Coulomb’s law is written as F= k_e (|q_1 ||q_2 |)/r^2 , where ke is 8.9875 x 109 N x m2 /C2. As shown in the equation, the separation distance of the charged particles is on the bottom of the fraction. This means that a greater distance would yield a lower force. Electricity can be classified in two different ways: static electricity or current electricity. In static electricity, there is a transfer of electrons between
Nikola Tesla was a Serbian American inventor, electrical engineer, mechanical engineer and physicist. He was also considered an eccentric genius and recluse. Tesla is best known for his feud with Thomas Edison over AC power Versus DC Power. He was also well known for inventing the Tesla Coil which is still used in radio technology today. Nikola Tesla was mostly forgotten until the 1990’s when there was a resurgence of interest in popular culture.
Nikola Tesla (1856-1943) was an eccentric man that was many lifetimes ahead of his generation. He was a man that dreamed of giving the world an unlimited supply of wireless energy. His genius imagination allowed him to think outside the box and solve issues that others had thought were unsolvable. Nikola Tesla proposed his vision for a system powered by an alternating current generator to Thomas Edison and was shot down because Thomas Edison’s power structure had already been established using a direct current system. The two butt heads however Nikola Tesla was relentless. After being used and rejected by Thomas Edison, Nikola Tesla picked himself and went toe to toe with the most prolific inventor. The stage for David vs Goliath was set. Through Nikola Tesla’s borderline obsession to solve the design for an alternating current motor and sacrificing his own opportunity to become a wealthy man, we now live in a very efficient world where everyone reaps the rewards of his genius, few know his name, and even fewer know what he did.
The world of science can be quite vast when comparing the various fields of study. One such field that intrigues the minds of many is electricity. From the days of Michael Faraday to the days of Nikola Tesla and Thomas Edison, the field of electricity continues to grow expontentially.

Inbound marketing, which is the primary marketing method used online, is largely active.
In 1799, Italian physicist Alessandro Volta made the first battery by piling alternating layers of zinc, cloth, and silver. This procedure, called a voltaic pile, was not the first device to generateelectricity, but it was the first to release a steady, current. However, there were some shortcomings in Volta's creation. The pinnacle at which the layers could be arranged was restricted because the mass of the pile would squash the brine out of the cloth. The metal discs also tended to crumble quickly, reducing the life of the battery. Despite these deficiencies, the SI unit of electromotive force is now called a volt in honor of Volta's accomplishment.
Edison is most famous for the development of the first electric light bulb. Like I said Edison was born into a time where America wasn’t very developed. He was born, and electricity had not been developed. But thanks to Edison when he had passed away on October 18, 1931 whole cities were lit up in electricity. For electricity, much of the credit goes to Edison.
The history of engineering goes back into the 19th century when Alexander Volta (1745-1827) made a remarkable discover regarding the nature of electricity (Cosgrove 749). He discovered that electrical current could be controlled and could flow from one point to another. By the time the mid-19th century came about the rules for electricity were being established. During this time electromagnetic induction was discovered by Michael Faraday who lived from 1791 to 1867 (749). Also during this time Samuel Morris invented the telegraph in 1837 which relies on the principles of electromagnetic induction (749). Alexander Graham Bell, who lived from 1847 to 1922, created the telephone which also uses electricity in order to operate (749). Through the success of the telephone, Bell Telephone Company was established. In 1878, the light bulb was finally invented by Thomas Edison who lived from 1847 to 1931 (749). Off the principles of Faraday’s electric motor from 1821, Nicholas Tesla invented a more efficient and powerful electric motor in 1888 (749). To make these inventions be more significant, effort was expended to make better motors and transformers and to enhance the power needed to make them function. Through these inventions during the middle 19th century, it led to the capability of lighting homes and cities through the use of electricity, and it also led to the creation of the telephone communication system (750).
Humans these days take electricity for granted. We don’t truly understand what life was like without it. Most young adults will tell you their life does not depend on electricity, but they aren’t fooling anyone. They all know that their life depends on electricity; whether it’s television, their phone, Google, or the lights in their house. We need to stop taking those things for granted and give credit where credit is due. That is why I chose to write about the scientists who contributed to the discovery of electricity, which then helped modern scientists fuel the electricity phenomenons we now have today.
Magnets are stones that produce magnetic fields. The magnetic field is invisible, but is responsible for the most noticeable aspect of a magnet: the attraction of a metal object or the repulsion of another magnet. Magnets are used in common everyday household items: credit cards, TVs, speakers, motors, and compasses. A magnets strength is measured by its magnetic moment. (“Magnetism”)
Electric currents produce magnetic fields, they can be as small as macroscopic currents in wires, or microscopic currents in atomic orbits caused by electrons. The magnetic field B is described in terms of force on a moving charge in the Lorentz force law. The relationship of magnetic field and charges leads to many practical applications. Magnetic field sources are dipolar in nature, with a north and south magnetic pole. The magnetic field SI unit is the Tesla, it can be seen in the magnetic part of the Lorentz force law F magnetic = qvB composed of (Newton x second)/(Coulomb x meter). The smaller magnetic field unit is the
The effects of electricity control much of our daily lives. Many of our gadgets and everyday tasks are run by this wonderful source of power. For example without electricity we would not be able to make a cup of coffee in the mourning, or even make a long distance call to family or friends. There have been several technological breakthroughs by many brilliant people throughout history regarding electricity. It has come from being discovered as a small current to being transformed into useful power to run such things as computers. Ben Franklin, Guglielmo Marconi, Thomas Edison, Paul Nipkow, and Charles Babbage have all contributed to the advancement of electricity, and all of their advancements have supplied society in many ways.
Magnetism was not studied or utilized before 1821 as it is today. A few hundred years ago people understood how magnets worked, but didn’t have many applications of the magnet because they were limited by the technology of their time. The applications of magnets today have opened a new door as to how we can harness the power of a magnet. I had a basic working knowledge of how magnets worked, such as polarity, but with researching different aspects of the magnet I have learned that we need to advance the potential capabilities of the magnet and fully understand how we can harness the magnet. In my research I looked at how a magnet works, the physics behind a magnet, the magnetic fields of Earth, why can’t magnets be used as energy, and magnets for pain relief benefits.
Proton precession magnetometer is used in finding objects which are buried, submerged or hidden from view. An object can be found directly where it is itself magnetic, or where it may displace material which is otherwise uniformly magnetic. In some cases an object may be found indirectly when it produces a magnetic anomaly as a consequence of it being buried or emplaced. Objects of search may involve a man-made iron or steel objects, an archaeological feature such as a brick, pottery or tomb or an intentionally buried magnet used for relocation purposes.
Lightning is the most powerful force you can imagine. Lightning is an electric current when cold and hot gases combine it makes and electrical charge also when frozen rain drops in the sky make collisions it also makes an electrical charge.
A magnet has an invisible field that forces other objects to respond to its properties. This powerful force, which is referred to as the magnetic field, has particles called electrons that actively shift and move within the field. These electrons constantly revolve around the poles, thereby creating energy that attracts objects. Because of this, a magnet has the ability to draw objects towards itself. This ability, which is called magnetism, is caused by the force field that magnets create through its protons (positive charge) and electrons (negative charge).
