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

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

already existent theories‚ such as electricity and magnetism. In addition‚ they have introduced new concepts by either creating them from scratch‚ or combining other theories. Electricity‚ for instance‚ is a form of energy fueled by the movement of charged particles‚ called electrons. It is an electrical current if these electrons flow from high to low voltage. If the charged

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

The Law of Navigation Law Number Four is called “The Law of Navigation.” The by-line for this chapter reads‚ “Anyone can steer the ship‚ but it takes a leader to chart the course.” That by-line reflects something that anyone can beat time‚ but not everyone is a conductor. Anyone can learn how to play a piano but not all will become a pianist. Everyone can learn to swing a golf club but not everyone can become a golfer. Regarding conducting‚ more than a few famous conductors have said that they can

The magnetic intensity needed to reduce to zero the magnetic flux density of a fully magnetized magnetic specimen or to demagnetize a magnet. d.)Retentivity -Magnetism that is introduced to iron is only temporary. Once the magnetism is removed then the iron will lose its magnetic strength over a set period of time. Were as magnetism induced in steel is permanent. Coercivity – Iron become demagnetized at 2 oersted Steel become demagnetized at 10‚000 H

(a)Ferromagnetic materials: Ferromagnetic materials have a large‚ positive susceptibility to an external magnetic field. They exhibit a strong attraction to magnetic fields and are able to retain their magnetic properties after the external field has been removed. Ferromagnetic materials have some unpaired electrons so their atoms have a net magnetic moment. They get their strong magnetic properties due to the presence of magnetic domains. In these domains‚ large numbers of atom’s moments (1012
