Electromagnetism built 28 days ago Retriever Science Physics Electromagnetism Electromagnetism is one of the fundamental forms of energy in the Universe. It changes characteristics radically depending on its frequency and wavelength, which correlate closely with each other. The term "electromagnetism" comes from the fact that electric and magnetic fields are closely intertwined, and, under many circumstances, it is impossible to consider the two separately. For instance, a changing magnetic field gives rise to an electric field; this is the phenomenon of electromagnetic induction, which underlies the operation of transformers. A more familiar example of electromagnetism in action would be the pickup used in electric guitars. Electromagnetic guitar pickups use a coil of wire, which senses any changes in the magnetic field created by a small permanent magnet. Source: sweetwater.com

ISCID Encyclopedia of Science and Philosophy BETA Make Entry Become an Editor Most Popular: ( Help Electromagnetism Electromagnetism is a scientific concept which describes the magnetism that an electric current produces. It is also a branch of physics that is focused on the study of the electromagnetic field produced by the combination of the magnetic field and the electric field that encompass all of space. Electric fields are produced by electric charges that are static, while magnetic fields are produced by electric charges that are in motion. The electromagnetic field exerts a force on electrically charged particles. That force is referred to as the electromagnetic force and is one of the fundamental forces that affect the universe, the other ones being strong nuclear force, weak nuclear force and gravitational force. These forces are the foundation from which any other form of force originates. Electromagnetism gets special mention, however, since it is affects interactions between atoms. Electromagnetism can be traced back to the 17th century, when it was first understood that magnetism and electricity were distinct concepts. But the theory as it is known today was developed over the years of the 19th century, concluding with what is now referred to as classical electromagnetism, guided by the equations referred to as Maxwell’s equations.

Its speed proved to be observer independent, a discovery which led to the overthrow of classical Newtonian mechanics, in which time was absolute. The aim of the course is to study Einstein's Special Theory of Relativity and Maxwell's electrodynamics, which have necessitated profound changes in our ideas of space and time. These theories together with Quantum Theory are essential for an understanding of modern physics. Synopsis Introduction to Maxwell's electromagnetic equations. Constancy of the speed of light.

Electromagnetism Introduction: So many devices and equipment around us are using electromagnetism as their driving force. Electric bells, buzzers, telephones, speakers, radios, and electric motors used in fans, hair dryers, vacuum cleaners and any other device that you can imagine are all using electromagnets. This project is an opportunity to learn more about electromagnets and find out what factors affect the strength of an electromagnet. Material and instructions: If you select electromagnetism as your project, you will have a large variety of choices for your experiment and display. For example you can make a simple electromagnet, make an electric catapult, take pictures of a magnetic field or make any other device that uses an electromagnet. Your display can include a drawing of your experiment and a working model that works and everyone can test. Materials needed for this project can be found at home or purchased locally. Most Electromagnet kits also have the necessary materials and step by step instructions on how to make any of the above subjects. Depending on how complete your kit is, you may need to purchase or gather some additional items to complete your project. You may

An example of how magnetic induction is used is in transformers. Two coils of wire are wrapped around an iron core. The primary coils are connected to the power supply while the secondary coils are connected to the device. An electromagnetic field is created from the primary coils and this induces a magnetic field in the core. This in turn induces a current in the secondary coil. The number of coils is proportional to the amount of voltage, so a transformer is used to increase or decrease the voltage. secondary voltage secondary turns primary voltage = primary turns Site Search: In association with: Computer Science Revision Revision Links and Tutors EFL Teaching / Learning Navigation: Home Contact KS2 Maths Advice ...

Home QG Seminar Research Teaching Lattice p -Form Electromagnetism and Chain Field Theory Derek K. Wise In p -form electromagnetism, we generalize ordinary electromagnetism by promoting the gauge potential A from a mere 1-form to a p -form. This gives an analog of the electromagnetic field which interacts naturally not with charged point particles, but with charged "( p -1)-branes". The most famous example other than ordinary electromagnetism is the Kalb-Ramond field ( p =2), which influences the motion of a charged "1-brane", i.e. a string The following paper considers a discrete version of p -form electromagnetism, based on ideas from lattice gauge theory and topological quantum field theory. p -form electromagnetism on discrete spacetimes Derek K Wise 2006 Class. Quantum Grav. Abstract: We investigate p -form electromagnetism-with the Maxwell and Kalb-Ramond fields as lowest-order cases-on discrete spacetimes, including the regular lattices commonly used in lattice gauge theory, but also more general examples. After constructing a maximally general model of discrete spacetime suitable for our purpose-a chain complex equipped with an inner product on ( p +1)-cochains-we study both the classical and quantum versions of the theory, with either

Site Map document.write('') Electromagnetic Interactions Fundamental electromagnetic interactions occur between any two particles that have electric charge. These interactions involve the exchange or production of photons. Thus, photons are the carrier particles of electromagnetic interactions Electromagnetic decay processes can often be recognized by the fact that they produce one or more photons (also known as gamma particles). They proceed less rapidly than strong decay processes with comparable mass differences, but more rapidly than comparable weak decays. Forces Within Atoms Electromagnetic interactions are responsible for the binding force that causes negatively charged electrons to combine with positively charged nuclei to form atoms. Forces Between Atoms Residual electromagnetic interactions between electrically neutral atoms are responsible for the binding of atoms to form molecules and most of the forces (apart from gravity) that we experience in everyday life. Molecular binding effects result from atoms sharing and/or exchanging electrons.

Moving Electrons Electricity is the movement of electrons from one place to another. Electrons are tiny particles found in an atom that have negative charges . Sometimes these electrons are released from an atom, leaving a positive ion and a free electron. In electricity, the electrons move from an area that is negatively charged (extra electrons) to an area that is positively charged (wanting electrons). That movement is electricity There aren't a lot of places that you can see electricity. The most common natural form of electricity is lightning . There are two basic forms of lightning, cloud to cloud and cloud to surface. Both are created when there is an unequal distribution of charges and the electrons move from one location to another. You can also see electricity in several labs with different apparatuses. Van de Graff generators are regularly used in museums and science classrooms to generate small arcs of electrons. Separating Charges Currents are created when there is a separation of positive and negative charges. Those electrons don't like to be bunched up. When they see a positive charge, they want to move. Batteries are a good example of separating charges. We use chemicals to create an environment where the electrons want to move. When you have connected the areas of positive and negative charges, you have created a
