There is no doubt that in the development and recognition of time‚ there have been many theories and periods that have defined the understanding of how it works and what is the driving force behind it. These factors have included the cosmological ideas of religions that have become the staples of cultures across the globe. They have also included Astrological factors such as the physical presence of ‚ but in more recent understandings science‚ physics‚ and the calculations of mathematics have lead

Aristotle attributed the first of what could be called a scientific 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

Electricity and Magnetism History Electromagnetism Originally electricity and magnetism were thought of as two separate forces. This view changed‚ however‚ with the publication of James Clerk Maxwell’s 1873Treatise on Electricity and Magnetism in which the interactions of positive and negative charges were shown to be regulated by one force. There are four main effects resulting from these interactions‚ all of which have been clearly demonstrated by experiments: 1. Electric charges attract

the ubiquity of electromagnetism. The properties of rubbed amber and the magnetism of lodestone were little more than curiosities until the 17th century. The elucidation of the nature of lightning and the recognition of light as electromagnetic radiation were even more recent. Yet our world is governed by electromagnetic interactions. All chemical bonds‚ the strength and weakness of materials‚ light‚ the influences that form and control living things are all aspects of electromagnetism. Indeed‚ only

Michael Faraday was the third son of a London blacksmith. He became a self- taught scientist whose greatest discoveries concerned electricity. In 1831‚ Faraday proved that magnets can be used to produce an electric current. This discovery enabled him to build an electric generator. It was a forerunner of the giant dynamos that keep the modern world supplied with power. Faraday was born on September 22‚ 1791‚ in Newington‚ England. When he was five‚ his family moved to London

magnetism and even light are all manifestations of the same phenomenon: the electromagnetic field. From that moment on‚ all other classic laws or equations of these disciplines became simplified cases of Maxwell’s equations. Maxwell’s work in electromagnetism has been called the "second great unification in physics"‚[2] after the first one carried out by Isaac Newton. Maxwell demonstrated that electric and magnetic fields travel through space in the form of waves‚ and at the constant speed of light

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
