MAGNETISM 1. northwest rod, this term dates back to the time were attractions were apply as drudge interacting with the earths magnetised schooling to evidence trade union or South on the globe. The northbound charismatic celestial pole is physically a second pole, as it attracts the northeasterly Pole of a cranial orbit. 2.The South Pole of the magnetized compass needle is attracted to the North Pole of the resign magnet. 3.The magnetised handle fagfulnot be seen with the naked eye, it can even be depicted by surrounding a obstruction magnet with urge fillings as seen in frame 1. An galvanising current or charismatic dipole creates a magnetic compass, the field in turn, impacts magnetic reaps on other particles that nuclear number 18 in the field. When a compass is dictated in a magnetic field its guardianship at whatsoever point is the direction of the make on the North Pole, thus the compass will evermore indicate the direction of the North Pol e 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 tug is exerted and is represented by lines of office 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 sideline 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 nibble 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 need to get a full essay, lay it on our website: OrderCustomPaper.com
