It is not easy feat to become an inspiration of Albert Einstein, considering that he is one of the most famous and recognized scientist. Of three people whose picture hung on Einstein’s wall, Michael Faraday was one of them. Although Faraday had come from a lower class in the 1800s, his eagerness to learn more about the world propelled him to great discoveries that changed the world. One of the most important findings for the future of both technology and the field of physics was Faraday’s breakthrough of the electromagnetic induction and his discovery of the magnetic field.
His concept of induction looks at the way changing magnetic fields can cause the current to flow in wires. Any change in the magnetic environment of a coil wire will cause a voltage to be induced in the coil. No matter how much is changed, a voltage will be generated. Faraday’s first set up of his lab did not induce current. He was able to hypothesize that a changing magnetic field was necessary to induce a current in a nearby circuit. He found the changes in the magnetic field and the size of the field were related to the amount of current created, which is also known as magnetic flux. The magnetic flux is the value that is the strength of the magnetic field multiplied by the surface area of the device. Michael Faraday was able to formulate the equation: E=dB/dt, where “E” is the value of the voltage induced, “dt” is the change in time, “dB” is the change in the magnetic flux. Basically, the amount of voltage created is equal to the change in magnetic flux divided by the change in time. The bigger the change you have in the field, the greater the amount of voltage.
In order to test his hypothesis, he made a coil by wrapping a paper cylinder with wire. He ...

...conductor, creating a current, which will further the rearrangement. Faraday noticed that he conductor charge did not influence anything that was enclosed within. He even went as far as constructing a room that was coated with metal foil and used a electrostatic generator to create a high-voltage discharge that stroked the outside of his metal foil-coated room. Michael found no electric charge on the inside walls and had used an electroscope to prove this.
Many things were able to develop successfully due to the Faraday cage. People were able to use the cage in microwaves, where it could trap the heat used for cooking. The metal wheel of the microwave acts as a Faraday cage. Also, electronic equipment can be shielded and protected form stray electromagnetic fields by using cables that contain a conducting shell that acts as a cage. Protective suits for linemen were

Essay on Physics Of The Field Of Education

- In the field of education, teachers use various tools to deliver their messages to students for a better understanding of the materials. In general physics classes at universities, one of the tools that are used to deliver the materials is a physics worksheet. A physics professor usually creates this worksheet to improve the abilities of students to solve physics problems and to use it as a guide for the exam. It contains two to three problems related to the materials covered in the class lectures....   [tags: Problem solving, Problem, University, Professor]

Essay Physics of the Human Body in Earth's Gravitational Field

- No Conclusion The force of gravity affects all "bodies" in the universe. How well each human falls into the imaginary line of gravity determines the energy they must have to expel to live within this force. The ideal axis for obtaining the greatest balance is one that is a strait line through the center mass of the body. This line should be identical to the one between the gravitational force between the body and the earth. The human body has adapted over many generations and there are markers that will show where a strait line should form to be properly aligned....   [tags: physics human gravity]

Magnetic Fields of Stationary Magnets Essay

- Missing figures/equations My goal in writing this paper is two fold. Goal one is to try and understand how a stationary magnet exerts force by means of a magnetic field (even across a complete vacuum). Frequently, electromagnetic fields are compared to the gravitational field. Goal two is to explore the similarities between the two types of fields to see if comparison throws any light on the mechanism of magnetic field generation. The term action-at-a-distance is often used to describe forces that travel through space and exert their effect without directly touching the objects acted upon....   [tags: physics science magnet magnetic field]

The Physics of the Arc Essay

- ABSTRACT Several researchers have devoted efforts on studying physics of arc and descriptive models are used to explain many arc welding related phenomena. However, due to the subject complexity, doubts still emerge about the mechanisms of some phenomena related to the arc. For instance, the description about electromagnetic interactions with the arc, which governs the arc trajectory and lead to plasma jet and arc blow formation, seems to be yet controversial. Thus, the present study aimed a better understanding of these phenomena....   [tags: Physics ]

The Curriculum Of The Ap Physics Course Essay

- Induced Electromotive Force The curriculum of the AP Physics course this academic year covered a large range of fundamental aspects of how the Universe works. This range varied from kinematics and work, to waves and electricity. Electricity was the last topic to be taught in the course, which struck a personal interest. This interest lead to further research in more advanced concepts of the nature of electricity. In the search, there was a hit with a concept the sparked familiarity from chemistry courses, induced current....   [tags: Magnetic field, Electromagnetism]

The Physics of Ultrasound Essay

- Without the use of physics in the medical field today, diagnosis of problems would be challenging, to say the least. The world of medical imaging in particular has benefited greatly from the use of physics. Ultrasound is sound waves that have a frequency above human audible. (Ultrasound Physics and Instrument 111). With a shorter wavelength than audible sound, these waves can be directed into a narrow beam that is used in imaging soft tissues. As with audible sound waves, ultrasound waves must have a medium in which to travel and are subject to interference....   [tags: Physics, Ultrasounds, medical, ]

Physics of Superconductors Essay

- As most people know (or don't know, whichever is the case) the component of an electrical circuit that causes energy loss is called "resistance," which can be defined as a materials opposition to current being passed through it. Usually, this resistance results in the production of heat, sound, or another form of energy. In many cases, this transformation of energy is useful in such applications as toasters, heaters, and light bulbs. Even though it is a useful property, resistance often gets in the way of performance in such cases as high voltage transmission wires, electric motor output, and other cases where internal system energy losses are unwanted....   [tags: physics superconductor]

Essay on The Physics of Soccer

- Rolling Motion and Friction Suppose you kick a soccer ball without giving it any spin. Your foot, therefore, gives the ball an initial speed (v) and an initial angular speed of 0. Since grass is not frictionless, the ball initially slides across the field, then starts to rotate and, eventually, starts rolling without slipping. A soccer ball rolls without slipping when its center-of-mass speed equals its angular speed (around its center of mass). OK, now suppose you want to kick the ball so that it immediately starts rolling without slipping....   [tags: physics sport sports soccer football]
