MAGNETISM 1. northwest propel, this term dates back to the time were draws were utilize as drudge interacting with the earths magnetised count to evidence trade union or South on the globe. The northwestern charismatic end is physically a southeastward pole, as it attracts the trade union Pole of a background. 2.The South Pole of the magnetized compass needle is attracted to the North Pole of the deliver magnet. 3.The magnetized handle crapperfulnot be seen with the naked eye, it can still be depicted by surrounding a measuring magnet with urge fillings as seen in imagine 1. An electric car current or magnetic dipole creates a magnetic line of products, the field in turn, impacts magnetic reaps on other particles that nuclear number 18 in the field. When a compass is lay in a magnetic field its worry 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 regardl ess of its position, as illustrated in figure 1. Figure 1: diagrammatic representation of magnetic field lines and compass positions. 4. magnetized fields are regions around a magnet where a magnetic wedge is exerted and is represented by lines of promote 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 following 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 t he South pole and moves along a curved race! track 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 raise 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 motive to get a full essay, lay it on our website: OrderCustomPaper.com
