Field

A magnetic field is produced in the region around a wire whenever a current flow through that wire. Magnetic fields are vector fields, they have a direction and magnitude. The formula for the magnitude of the magnetic field from a wire is B=(µ_O I)/2πr. B is the magnetic field, µ_O is the permeability of free space (4πx〖10〗^(-7)Tm/A), I is the current, and r is the distance from the field sensor to the rod. In part 1A and 1B we constantly turn off the power source and ammeter after each run to eliminate

Theory A magnetic field is an area in which there is an electrical charge where a magnetic force acts. A magnetic field can be induced in a circular loop and it can be calculated if the radius, current, and number of turns are all known. When in the form of a coil it is directed along the axis of the coil and is usually uniform throughout the coil until it begins to fall off when it gets further away from the center. Another characteristic of magnetic field is that it can be changed to induce a

of this lab experiment was to study the magnetic field that surrounds a magnet and to see how the strength of the magnetic field change with distance from a magnet. The experiment was successful in achieving its purpose and in proving the theory of the experiments. In the experiment that we needed to show the magnetic field surrounding a magnet, we used a piece of paper, a magnet, and a compass to show the magnetic field. To view the magnetic field that is surrounding the magnet, we placed the magnet

in it and began researching and designing. The motion of the Maglev train is based purely on magnetism and magnetic fields. This magnetic field is produced by using high-powered electromagnets. By using magnetic fields, the Maglev train can be

trip to Wrigley Field on the north side of Chicago. Wrigley Field is known as the friendly confines by many baseball fans. Built in 1914, Wrigley Field is one of the most celebrated baseball stadiums in Major League Baseball (MLB) history. Several key factors have contributed in making Wrigley Field what it is today. Some of the key factors: the owners, the stadium features, the players, the broadcasters, the historical games, the fans, and community have all helped make Wrigley Field special. Wrigley

through it, is placed in a magnetic field a force is placed on the wire: this is the motor principle and this is the principle behind the loud speaker. Hello, My name is Michael Trevorrow and you will be learning about the loud speaker and electromagnetism. But first, if you want to understand the loud speaker you have to understand electromagnetism. Well electromagnetism is simply ‘the phenomenon of the interaction of electric currents or fields and magnetic fields’. This will become clearer later

the scope of this document is field recording. A literal interpretation (i.e., to record in a field) falls short of what is encompassed. In contrast to the type of recording with which many musicians may be familiar, within a highly controlled space exhibiting minimal extraneous sound, field recording is audio recording conducted outside a recording studio. This comes without exception, acquiring sounds produced by life, nature, or anything else present. Noted field recordist and ecologist Bernie

FieldsIn Flanders fields the poppies blow Between the crosses, row on row,That mark our place; and in the skyThe larks, still bravely singing, flyScarce heard amid the guns below.We are the Dead. Short days agoWe lived, felt dawn, saw sunset glow,Loved, and were loved, and now we lieIn Flanders fields.Take up our quarrel with the foe:To you from failing hands we throwThe torch; be yours to hold it high.If ye break faith with us who dieWe shall not sleep, though poppies growIn Flanders fields.

Report: Electric Field Mapping Andie Zoeller 09/09/2014 Essence: The objective of this lab was to map out certain points of voltage that were determined by the equipotential surfaces. By doing this, with the probe on a multi-meter, we were able to see where the equipotential lines were at in accordance to the objects (metal cylindrical conductor, metal rectangular conductor, etc.) With this gathered information we were able to point out where the lines of the electric field were. We were
