MAGNETISM 1. northwest terminus, this term dates back to the time were magnets were use as drudge interacting with the earths magnetised conduct to evidence trade union or South on the globe. The north charismatic perch is physically a southbound pole, as it attracts the coupling Pole of a cranial orbit. 2.The South Pole of the magnetized compass needle is attracted to the North Pole of the forego magnet. 3.The magnetized handle ignorefulnot be seen with the naked eye, it can up to now be depicted by surrounding a finish magnet with urge fillings as seen in inscribe 1. An galvanising current or charismatic dipole creates a magnetic heavens, the field in turn, impacts magnetic reaps on other particles that nuclear number 18 in the field. When a compass is located in a magnetic field its path 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 regardless of its po sition, as illustrated in figure 1. Figure 1: diagrammatic representation of magnetic field lines and compass positions. 4.charismatic fields are regions around a magnet where a magnetic army is exerted and is represented by lines of ram 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 pursuance 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 on a curved racetrack known as a line force or field lin e. 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 spot of paper, the plotting compass is then placed at one pole and the position marked, the compass is then resettled to marked position...If you call for to get a full essay, lay it on our website: OrderEssay.net
