Williams Project 1 The use of electricity and magnetism in transportation When Benjamin Franklin discovered electricity‚ it was probably one of the biggest discoveries known to mankind. Even though our dependence of electricity is a lot‚ however at the same time it’s easy to forget how dependent we actually are on it. Electricity always has and always will play a huge part in our everyday life. It’s hard to imagine humanity without it. When it comes to transportation‚ it is going to rewrite the

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

What is Magnetism? Properties of Magnets: Magnet: any material that attracts iron and materials that contain iron Magnets attract iron and materials that contain iron. magnets attract or repel other magnets. In addition‚ one part of a magnet will always point north when allowed to swing freely. Magnetic Poles: Magnetic Pole: any magnet with 2 ends‚ each is called a magnetic pole. Magnetic poles that are unlike attract each other and magnetic poles that are alike repel each other. Magnetic

Electricity and Magnetism Electricity Circuit symbols Potential difference The energy which is delivered to an electric circuit comes from the supply. The greater the potential difference of the power supply the more energy is delivered. Potential difference is measured in volts‚ which has the unit symbol V. Cells in series The more chemical cells that are connected in series the greater the potential difference that they supply. The potential difference of a number of cells connected

Electromagnetism and Modern Technologies The invention of electricity has benefited mankind in several aspects of life ever since the 1800s. Over the course of the past two centuries‚ scientists have been developing theories that serve as the backbone for various devices today. Such intellectuals have been attempting to understand the credibility and applicability of the already existent theories‚ such as electricity and magnetism. In addition‚ they have introduced new concepts by either creating

Electricity and magnetism are two different aspects of one force. This force is called the electromagnetic force. Electricity can be generated by rotating coils of wire in the vicinity of a magnet. When a force moves objects toward and away from each other it is called electricity. When it comes to magnets‚ Earth and other planets behave like giant magnets. The first know magnets were iron materials. If one piece of the iron was placed in contact with the other‚ it attracted it. In ancient times

Electricity and magnetism run nearly everything we plug in or turn on. Although it’s something we take for granted‚ it has taken hundreds of years of experimentation and research to reach the point where we flick a switch and the lights go on. Ancient Greeks knew rubbing amber generated static electricity‚ but they didn’t know why. The Greek word for amber is elektron. People knew about electricity for a long time. Ancient Greeks noticed that if they rubbed a piece of amber‚ feathers would

Why is magnetic flux through closed surface zero while electric flux not? Gauss’ Law for Magnetism The net magnetic flux out of any closed surface is zero. This amounts to a statement about the sources of magnetic field. For a magnetic dipole‚ any closed surface the magnetic flux directed inward toward the south pole will equal the flux outward from the north pole. The net flux will always be zero for dipole sources. If there were a magnetic monopole source‚ this would give a non-zero area integral

The technology is already pointing toward what carmakers and futurists call augmented reality. Heading into the future A report released earlier this year by TechNavio‚ a technology research firm‚ noted that HUDs would gain popularity over the next few years as the technology was introduced into more mid-range models‚ which would in turn lower system prices.
