J.G. Fichte‚ the founder of German idealism‚ called animal magnetism “the physicalization of idealism” (pg 93). Invention of telegraph and radio a new way of communication appears for human being.

HOW AN ELECTRIC GENERATOR WORKS Electrical generators by definition are devices that convert mechanical energy into electric energy. The mechanical energy in turn is produced from chemical or nuclear energy in various types of fuel‚ or obtained from renewable sources such as wind or falling water. Steam turbines‚ internal-combustion engines‚ gas combustion turbines‚ electric motors‚ water and wind turbines are the common methods to supply the mechanical energy for such devices. Generators

a man who is known for making a great deal breakthroughs in the wide variety of his work in both mathematics and physics. He is responsible for immeasurable contributions to the fields of number theory‚ analysis‚ differential geometry‚ geodesy‚ magnetism‚ astronomy‚ and optics‚ as well as many more. The concepts that he himself created have had an immense influence in many areas of the mathematic and scientific world. Carl Gauss was born Johann Carl Friedrich Gauss‚ on the thirtieth of April

solids with our fingers. We needed to find the density‚ magnetism‚ and malleability of the solids. We used water displacement to find the volume of each of the insoluble solids. We then found the mass of the solids‚ then divided the mass by the volume and found the density. Density’s- Nut- 6.9 g/cm^3‚ Marble- 2.06 g/cm^3‚ silver pellets- 0.4 g/cm^3. We tested magnetism by using a magnet‚ and malleability by smashing each solid with a hammer. Magnetism- Nut- yes‚ marble- no‚ Pellets- no. Malleability- Nut

trichromatic lighting and in color TV tubes. It also makes the green color on your Blackberry or other high definition screen. Hybrid car engines have electric motors and all electric motors are based on magnets. These magnets need to retain their magnetism at high temperatures. Alloying neodymium with terbium and dysprosium produces such magnets. These magnets are also used in the electric motors of wind-turbines‚ where high temperatures are also generated. Terbium is one of the rarer rare-earth elements

He lived during the Enlightenment era‚ and he was the first to offer a rational explanation for hypnosis. He believed that hypnosis involved ‘animal magnetism’‚ an energy that is passed from the hypnotist to the patient by using a magnet. This belief was based on the prevailing scientific ideas of that time‚ particularly Newton’s theories of gravitation. Mesmer began using hypnosis to heal his patients

Magnetism and Electrostatic The three things I learned from the lesson was that magnetism is a natural force that causes magnets to function; the different turns that describes the properties of magnets; and the Greek philosopher who have been discovered the properties of lodestone. There are ways that I can relate my learnings to my everyday life; using magnet to find small pieces of metallic objects and using electric motor to convert electrical energy for our everyday use.

Electricity’s impact on Society Electricity has had multiple impacts on society both positve and negative. Electricity has had an effect on everyone in the world‚ even though some people have no understanding or have no use for electricity. For example‚ there are tribes in the Amazon who have never seen a lightbulb who have never beared witness too the heracy of Big brother and yet they are still effected by electricity. The chainsaws which cut down their beloved forests are designed by a man called
