Fuel is one of the important resources in our society. We use the fuels to support our living‚ produce electricity‚ heat homes‚ and operate machinery. Since the fuel is a limited resource‚ the fuel scarcity will be a big issue in the future. The price of the gasoline is currently on the rise. NASCAR cut the volume of fuel cell from twenty gallons to thirteen gallons each car. There is a high demand for a new energy. After the issue of fuel crisis was brought up‚ the society started to be interested

Ferro-Para-Di-Magnetism Magnetism is defined in the dictionary as the class of phenomena exhibited by a magnetic field. In physics there are a few types of magnetism. In this paper only three types will be covered which are ferromagnetism‚ paramagnetism‚ and diamagnetism. Ferromagnetism is considered the strongest type of magnetism‚ as it is a permanent magnet. A permanent magnet is one that remains a magnet after being magnetized by an outside magnetic field. Ferromagnetism is a type of magnetism that

speaking about magnetism and its use in our everyday lives‚ you can learn the SECRETthe secret of magnetism! A true scientist would be glad to share his secrets through experimentation. Thus‚ I will share the secret with you. It begins with sciencephysics‚ to be exact: matter and energy‚ conduction and induction‚ magnetizing and demagnetizing. All will be explained in my science project. More importantly‚ to discover through experimentation that the secret behind magnetism could be its power

discussion on magnetism to Thales of Miletus‚ who lived from about 625 BC to about 545 BC.[1] Around the same time‚ in ancient India‚ the Indian surgeon‚ Sushruta‚ was the first to make use of the magnet for surgical purposes.[2] There is some evidence that the first use of magnetic materials for its properties predates this‚ J. B. Carlson suggests that the Olmec might have used hematite as a magnet earlier than 1000BC[3] [4] In ancient China‚ the earliest literary reference to magnetism lies in a 4th-century

Title : How to reduce use of Electricity Introduction Electricity is a secondary source of energy. Primary sources of energy are oil‚ coal‚ uranium or the forces of nature. Energy is a source of usable power‚ needed for food production‚ transportation‚ heating‚ cooling‚ and lighting. The largest sources of energy in the world are oil (34%)‚ coal (26.5%)‚ and gas (20.9%)1‚ adding up to over 80% of global energy. These types of fuels are called fossil fuels because they are found in fossil

ELECTRICITY MR.ROBINSON Electricity is the set of physical phenomena associated with the presence and flow of electric charge. Electricity gives a wide variety of well-known effects‚ such as lightning‚ static electricity‚ electromagnetic induction and the flow of electrical current. In addition‚ electricity permits the creation and reception of electromagnetic radiation such as radio waves. In electricity‚ charges produce electromagnetic fields which act

Basics of Magnetism by Ron Kurtus (revised 29 January 2013) Magnetism is a force of attraction or replusion that acts at a distance. It is due to a magnetic field‚ which is caused by moving electrically charged particles. It is also inherent in magnetic objects such as a magnet. A magnet is an object that exhibits a strong magnetic field and will attract materials like iron to it. Magnets have two poles‚ called the north (N) and south (S) poles. Two magnets will be attacted by their opposite poles
