Electricity and magnetism run nearly everything we plug in or turn on. Although it’s something we take for granted‚ it has taken hundreds of years of experimentation and research to reach the point where we flick a switch and the lights go on. Ancient Greeks knew rubbing amber generated static electricity‚ but they didn’t know why. The Greek word for amber is elektron. People knew about electricity for a long time. Ancient Greeks noticed that if they rubbed a piece of amber‚ feathers would

Types of Magnets Objects having magnetic field is called as magnets. Normally magnets are of two types- Permanent magnets and Electro magnets. Permanent magnets are those magnets which occur in nature and do not depend upon external source for their magnetic field. On the other hand electromagnets are those magnets which use electric current to generate magnetic field. Classification of Magnets There are different types of magnets with different physical and magnetic properties and strength

2.1 Motors use the effect of forces on current-carrying conductors in magnetic fields 2.1.1 The motor effect The motor effect is where a force acts on a current-carrying conductor in a magnetic field. The right hand palm rule is used to find certain properties: fingers point to magnetic field‚ thumb points in DC direction and palm points to direction of the force. 2.1.2 Factors affecting the force acting on the current-carrying conductor Forces are experienced by the electrons in the conductor

The Magnet Compass Research Paper Many people believe that the magnetic compass is one of the most important inventions ever created‚ next to penicillin and the panini maker. It turns out that there is an entire story that lies behind this marvelous invention’s history and how it works. When most people think about a compass‚ they think of “that thing that shows which way is north”. But the truth is that it’s much‚ much more than that. This is an example of how much we take the things we have

CHAPTER 1: INTRODUCTION 1. Magnetic Abrasive Finishing (MAF) Surface roughness of parts produced by conventional machine tools‚ depends n the machine tool system and the cutting process. It is difficult to produce a smooth surface on complicated profiles at an economic cost by using conventional machining processes. This and the advent of new ‘ difficult-to-machine’ materials like hardened steel‚ nickel‚ cobalt‚ titanium alloys‚ ceramics‚ glass‚ etc.‚ have necessitated the need for

MAGNETIC MAGNETIC REFRIGERATION a fruitful approach to reduce environmental pollution... ABSTRACT : The objective of this effort is to determine the feasibility of designing‚ fabricating and testing a sensor cooler‚ which uses solid materials as the refrigerant. These materials demonstrate the unique property known as the magneto caloric effect‚ which means that they increase and decrease in temperature when magnetized/demagnetized. This effect has been observed for many years and was used for cooling

HEAVY METAL MUSIC WHAT IS HEAVY METAL MUSIC? Heavy metal (often referred to simply as metal) is a genre of rock music that developed in between 1968 and 1974 ‚ largely in the United Kingdom and the United States.With roots inblues-rock and psychedelic rock‚ the bands that created heavy metal developed a thick‚ massive sound‚ characterized by highly amplified distortion‚ extended guitar solos‚ emphatic beats‚ and overall loudness. Heavy metal lyrics and performance styles are generally associated
