Wire In A Magnetic Field
2,554 wordsPlanning Aim and hypotheses According to Fleming's Rule, electricity is generated when movement occurs in the magnetic field. Alternatively, switching direction of the magnetic field also works. Alternating current is a good way of alternating the field direction. The electricity generated, of in the other words, the electromotive force, is measured in volts. By varying different parts of the apparatus, the EMF output could also vary. The aim of this investigation is to establish a connection be...
Magnetic Field Around A Single Wire
1,305 wordsResearch, p. 1 Do you want to know a secret? First, consider this: When a magician performs a magic trick, many ask, "How did he do that?" Well... the true magician never tells because it is a secret. But when speaking about magnetism and its use in our everyday lives, you can learn the SECRET-the secret of magnetism! A true scientist would be glad to share his secrets through experimentation. Thus, I will share the secret with you. It begins with science-physics, to be exact: matter and energy,...
Low Magnetic Fields
1,736 wordsSuperconductivity INTRODUCTION We " ve all heard about superconductivity. But, do we all know what it is? How it works and what are its uses? To start talking about superconductivity, we must try to understand the how 'normal' conductivity works. This will make it much easier to understand how the 'super' part functions. In the following paragraphs, I will explain how superconductivity works, some of the current problems and some examples of its uses. CONDUCTIVITY Conductivity is the ability of ...
702 wordsHans Christian Oersted was born in Rudkobing on August 14, 1777 to Soren Christian Oersted and Karen Herman sen. His father was an apothecary and did not have the time to properly raise Oersted or his brother so they were raised by a German wigmakers. When he turned eleven, he went to work for his father at his pharmacy, where his first interest in science began. Without any prior schooling, except what he learned informally through others, he passed the entrance exam to University of Copenhagen...
Magnetic Disks In Computers
1,164 wordsMagnetic Disks (Hard Disk) The topic of magnetic disks is one that involves many physics related phenomenon. The intricate structure and design of "Magnetic Disks" (or hard disks) in computers include the principles of Fluid Flow, Rotational Motion, Electromagnetism, and more. This paper will focus mainly on the previously listed physics occurrences, and the design that goes into engineering the magnetic disk to include them. These physics principles are utilized in such a way that makes the har...
Fields Of Electricity And Magnetism
579 wordsMichael Faraday is a British physicist and chemist, best known for his discoveries of electromagnetic induction and of the laws of electrolysis. He was born in 1791 to a poor family in London, Michael Faraday was extremely curious, questioning everything. He felt an urgent need to know more. At age 13, he became an errand boy for a bookbinding shop in London. He read every book that he bound, and decided that one day he would write a book of his own. He became interested in the concept of energy...
Electromagnets And Permanent Magnets
1,134 wordsFor Levitation In ancient times men knew of a special kind of rock that could pull other rocks of the same kind and pieces of iron toward themselves. Such rocks were called lodestones. Today man uses the same force exerted by electromagnets and permanent magnets to provide magnetic aide to trains and more efficient power generators. This report will focus on the use of magnets in the generation of electricity and magnetically aided trains. Magnetism is defined as the force exerted by a magnetic ...
Current On The Effectiveness Of An Electromagnet
1,222 wordsWhat Is The Effect Of Increasing The Current, On The Effectiveness Of An Electromagnet When Picking Aim Question: What is the effect of increasing the current, on the effectiveness of an electromagnet when picking up steel pins Originally the idea was to count the pins that the electromagnet picked up, but this proved too difficult. Because of this, we decided to weigh the pins that had been attracted instead. Predictions First of all, an electromagnet has to be defined. An electromagnet can als...
Work Opportunities Within The Electrical Engineering Field
1,730 wordsFrom the beginning of human existence, man has identified ways to improve the standard of living. Electricity was one of these identified ways. The development of electricity led to the creation of electrical engineering, a challenging vocation that changed and improved our way of life. In this paper I will discuss the history of electrical engineering, the preparation for becoming an electrical engineer, and the actual career. The history of electrical engineering is rather recent, but it is ba...
