What is a magnet? Magnet is an object that can create magnetic field by itself. It is usually made from iron. It had a pulling force called magnetism. The pulling force is able to pull at certain things like objects made of iron or steel. It can attract or repel other magnetic objects that are not even magnetized and of course other magnets too. Due to the characteristic of a magnet, it can give a great impact to our world. It has many benefits to the industrial field, the transportation in our modern

India’s large urban population has left our systems of public transport is extremely overwhelmed, demands far exceeding the limited supply of transport infrastructure and services, absconding most buses and trains services as overcrowded, undependable and dangerous. Our cities desperately need improved and expanded public transport services. However “With 23 percent of its urban population living in poverty, India has been forced to keep its public transport fares extremely low. Making it difficult

3. DATA AND METHODOLOGY 3.1. Magnetic Data The used data are based on the reduced to pole (RTP) aeromagnetic data (Fig. 2) with contour interval of 20 nT, scale 1:250,000 (total field of the area is 41,400 nT, inclination angle is 37.4 degrees and declination angle is +1.6 degrees). The magnetic data was compiled for the Eastern Desert and the Red Sea, based on Meshref (1990) and available in Saad (1991). The Union Oil Company carried out this survey in 1974. Fig. (2): 3.2. Determination of the

magnetism actually it. But there are plenty of metals that don’t stick to a magnet. Yes, that’s true, though ‘magnetic’ in this sense means something a little different. Metals that don’t stick to magnets are known as ‘non-ferrous metals’. Some of these metals include copper, aluminum, lead, and nickel along with alloys such as brass. These metals share many similarities, but the one that keeps them from sticking to magnets is the fact that they don’t have trace amounts of iron in them. The iron is

Levitating is not only for magicians, but for magnets too. Scientist have been using magnetism to create levitation for years. Recently, they have advanced their technology and expanded their knowledge about magnetism and levitation and conformed them to be used in everyday life. Magnetic levitation can be broken down into so many different topics such as magnetism and levitation, but there is a much deeper meaning to magnetic levitation. A magnet is an object that has a magnetic field. It can

1. Bar magnet is the simplest form to explain magnetism. Bar magnets are permanent magnets and this means that they have magnetism all the time, it can’t be turned on and it can’t be switched off. They have two poles that include: north-seeking pole (N) and south-seeking pole (S). These poles appear to occur in equal and opposite pair. Magnetic meridian is the vertical plane in which the magnet lies. Magnets are made of materials that can be magnetized, which are also the ones that can be attracted

Makes a Magnet? by Franklyn M. Branley. After the read aloud, students were dismissed for centers and groups of five students circulated through completing the lesson activity. For this lesson, the objective and sub-objectives were as follows: • After completing this lesson, students will be able to sort magnetic and nonmagnetic objects by using a magnet with 100% accuracy. o Students will define the following vocabulary words: magnet, magnetic, nonmagnetic o Students will be able to use a magnet to find

easily understood, but none the less intriguing. Magnets have intrigued people for a long time; they were discovered long ago. Certain rocks and ores of iron called lodestones were found. These lodestones which were naturally magnetic rocks made of the mineral magnetite, were so mysterious to

Introduction A magnetic bearing is a type of bearing that holds up a load using magnetic levitation. Scientists first discovered the magnetic effects in magnetic minerals in 500B.C. In the late 20th century, scientists began developing ways where this magnetic effect could be implemented into a bearing, creating magnetic bearings. Today, magnetic bearings can be found in many applications where no physical contact is required or extreme environmental conditions exists, including very high and low
