Magnetic Field Opposite Direction
1,217 wordsThe phenomenon called electromagnetic induction was first noticed and investigated by Michael Faraday, in 1831. Electromagnetic induction is the production of an electromotive force (emf) in a conductor as a result of a changing magnetic field about the conductor and is a very important concept. Faraday discovered that, whenever the magnetic field about an electromagnet was made to grow and collapse by closing and opening the electric circuit of which it was a part, an electric current could be ...

Uv Radiation Electromagnetic Fields
2,154 wordsBiohazards. The mankind has been experiencing the technological boom since 60 of the last century. This boom touched upon almost all the spheres of our life. New machines and equipment were developed to make our life better. The development of science and technology caused new hazardous factors for the human beings which were unknown before. New hazardous materials with the perfect technological qualities influence the man hazardously; the nuclear power generation appeared to be the perfect powe...

White Light Red Green
1,468 wordsColor is the curves, where the height of the curve represents the amount, or intensity, of that particular wavelength. Everyone of these distribution curves then corresponds to a color of light. Many of the colors we are familiar with appear on the EMF visible spectrum, such as red and yellow. We would therefore expect the distribution curves of these colors then to have a positive value only at a certain wavelengths. Under most conditions this is not true there are usually traces of all the oth...

Cycles Per Second Magnetic Fields
2,862 wordsThe Effects of Living Under Electro Magnetic Fields Power Lines Electric power is a fact of life in America in the world today. Ever since electric power was introduced society has thought nothing of the harmful effects of electromagnetic fields or electricity as long as they had it at their disposal. I will not be able to answer the question for you about how harmful it is but I will be able to enlighten you with information to help you decide how harmful it really is. For many years there have...

Risk Of Contracting Magnetic Fields
399 wordsHomes are filled with electric magnetic fields (EMFs), EMFs are created every time anything electrical is used. Hair dryers, alarm clocks, micro waves and radios are just a few examples. All these appliances cause leukemia, a form of cancer. High EMF fields are not very unusual. EMFs can pass through walls, so one can also be exposed to them from power lines and transformers. Using a hair dryer for 3 minutes would give the same exposure that one would get living next to a high voltage power line...

Speed Of Light Lightning Bolt
3,469 wordsElectricity Electricity WHAT IS ELECTRICITY Electricity is a form of energy. Thats because we can use electricity to do things for us, like run machines and computers. Electricity also can be transformed into other types of energy such as heat or light and is used to heat our homes, light our cities and towns and power the computers we are using. Electricity is the type of energy that is invisible. Its made of moving electrons that are so small and move so fast that we cannot see them. The elect...

Magnetic Field Generate Electricity
2,438 wordsPlanning Aim and hypotheses According to Flemings Rule, electricity is generated when movement occurs in the magnetic field. Alternatively, switching direction of the magnetic field also works. Alternating current is a good way of alternating the field direction. The electricity generated, of in the other words, the electromotive force, is measured in volts. By varying different parts of the apparatus, the EMF output could also vary. The aim of this investigation is to establish a connection bet...

Power Supply Magnetic Field
1,679 wordsPlanning Aim To find the factors that affect the amount of E. M. F. being produced. The amount of E. M. F. produced during the experiment when each type of factors is change. Background knowledge Electro-motive-force is the energy being supply to a charge. Battery is a type of energy. The energy that it provides is voltage. Battery voltage is sometime called electro-motive-force because it is used to pump around the electrons in the wire. The force can be generates by the moving of magnetic fiel...

Living Near Powerlines Children With Leukemia Scientists
530 wordsELECTRICITY ESSAY The Powerline Controversy There has been a great scientific uproar lately about the link between powerlines and EMF (Electro-Magnetic Fields, generated by all electrical appliances) and Leukemia and other types of cancers. Some scientists suggest that people living near powerlines and a lot of electrical appliances are two or even more times likely to get cancer than people that dont live near as many sources of EMF. Though it hasnt been fully proven, scientists keep researchin...

Play A Role Chemical Reactions
1,867 wordsPROBLEM: BATTERIES TEND TO FAIL AT EXTREME TEMPERATURES. TESTABLE QUESTION: HOW AND WHY DO DIFFERENT BATTERY TYPES FAIL AT EXTREME TEMPERATURES? ELECTRO CHEMISTY BATTERY FAILURE HONORS CHEMISTY RESEARCH PROJECT HISTORY OF THE BATTERY The battery s origins may be followed back to very ancient times. We know that many of the wise men could have been exploring and testing electricity. For example, a clay vase, thought to be several thousand years old, was discovered in 1932 near Baghdad. It contain...
