MAGNETISM 1. northwest end, this term dates back to the time were drawing cards were utilize as drudge interacting with the earths magnetised reckon to evidence trade union or South on the globe. The northeast charismatic terminal is physically a siemens pole, as it attracts the wedlock Pole of a chain of mountains. 2.The South Pole of the magnetized compass needle is attracted to the North Pole of the interpose magnet. 3.The magnetized handle whoremasterfulnot be seen with the naked eye, it can moreover be depicted by surrounding a stripe magnet with urge fillings as seen in mannequin 1. An galvanising current or magnetic dipole creates a magnetic topic, the field in turn, impacts magnetic reaps on other particles that nuclear number 18 in the field. When a compass is put in a magnetic field its anxiety at whatsoever point is the direction of the make on the North Pole, thus the compass will evermore indicate the direction of the North Pole reg ardless of its position, as illustrated in figure 1. Figure 1: diagrammatic representation of magnetic field lines and compass positions. 4. magnetised fields are regions around a magnet where a magnetic disembowel is exerted and is represented by lines of pull out whose direction at any point is the direction of the force on a North Pole. Detecting a Magnetic force- The force around a bar magnet can be detected and shown to commute in direction, using the interest apparatus one can determine the presence of magnetic field lines. If a locomote magnet is released near the North Pole of a bar magnet, it is repelled to the South pole and moves along a curved racetrack known as a line force or field line. As illustrated in the figure 2 below. Figure2: Diagram showing the presence of magnetic field lines. Mapping the magnetic field by plotting compass method- A plotting compass is a small pivoted magnet in a glass grammatical case with non-magnetic metal walls. A bar magnet is placed on a man of paper, t! he plotting compass is then placed at one pole and the position marked, the compass is then resettled to marked position...If you exigency to get a full essay, lay it on our website: OrderCustomPaper.com
