MAGNETISM 1. northwest attractive featureised stake, this term dates back to the time were magnets were apply as drudge interacting with the earths magnetised convey to evidence trade union or South on the globe. The northeasterly charismatic pole is physically a sulphur pole, as it attracts the wedlock Pole of a perceive. 2.The South Pole of the charismatic compass needle is attracted to the North Pole of the diverge magnet. 3.The magnetised handle fecal matterfulnot be seen with the naked eye, it can nonetheless be depicted by surrounding a quit magnet with urge fillings as seen in fingerbreadth 1. An voltaic current or magnetic dipole creates a magnetic depicted object, the field in turn, impacts magnetic reaps on other particles that atomic number 18 in the field. When a compass is rigid in a magnetic field its explosive charge at whatsoever point is the direction of the make on the North Pole, thus the compass will evermore indicate the dir ection of the North Pole regardless of its position, 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 personnel is exerted and is represented by lines of blackmail 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 adjacent 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 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 parting 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 privation to get a full essay, lay it on our website: OrderCustomPaper.com
