More advantages over the other types of magnet in many applications in modern products that require strong permanent magnets, such as motors in cordless tools, hard disk drives and magnetic fasteners. Neodymium magnets can be used to invent a new method of energy generation by using the magnetic field of magnet and convert the magnetic energy into kinetic energy without using any kind of fuel and overcoming the energy generation problem such as building a magnetic turbine. The main objective of the study was to study about the advantage of using NdFeB magnets over normal magnets, nature of different type of neodymium magnets and how it can be used to convert magnetic energy into kinetic energy.

INTRODUCTION Certain materials found in nature exhibit a tendency to attract or repeal each other. These materials, called magnets, are also called ferromagnetic because they include the element iron as one of their constituting elements. Magnets always have two poles north & south. Like poles always repel each other. However, unlike poles attract each other. A Magnetic field is defined as a physical field established between two poles. Its intensity and direction determine the forces of attraction or repulsion existing between the two magnets. A neodymium magnet (also known as NdFeB, NIB or Neo magnet), the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron to form the Nd 2 Fe 14 B tetragonal crystalline structure. Neodymium magnets are metal, and they are colored silver, like most other metals. Developed in 1982 by General Motors and Sumitomo Special Metals, neodymium magnets are the strongest type of permanent magnet commercially available. They have replaced other types of magnet in the many applications in modern products that require strong permanent magnets, such as motors in cordless tools, hard disk drives and magnetic fasteners. Rare Earth magnets (also known as Neodymium magnets) are 5 to 7 times stronger than Ferrite Magnets and offer the greatest value for money II. GRADES Figure 1 Neodymium Magnet Neodymium magnets are graded according to their maximum energy product, which relates to the magnetic flux output per unit volume. Higher values indicate stronger magnets and range from N35 up to N52. Letters following the grade indicate maximum operating temperatures (often the Curie temperature), which range from M (up to 100 degrees Celsius) to EH (200 degrees Celsius). Neodymium magnets are metal, and they are colored silver, like most other metals. Hematite is not a metal, although it has some metal atoms in it. It is instead a
