The Universe of Discourse Mark Dominus mjd@plover.com RSS ... Freshman electromagnetism questions Archive: J J F M ... J A S O N D ... D Fri, 07 Dec 2007 Freshman electromagnetism questions As I haven't quite managed to mention here before, I have occasionally been sitting in on one of Penn's first-year physics classes, about electricity and magnetism. I took pretty much the same class myself during my freshman year of college, so all the material is quite familiar to me. But, as I keep saying here, I do not understand physics very well, and I don't know much about it. And every time I go to a freshman physics lecture I come out feeling like I understand it less than I went in. I've started writing down my questions in class, even though I don't really have anyone to ask them to. (I don't want to take up the professor's time, since she presumably has her hands full taking care of the paying customers.) When I ask people I know who claim to understand physics, they usually can't give me plausible answers. Maybe I should mutter something here under my breath about how mathematicians and mathematics students are expected to have a better grasp on fundamental matters. The last time this came up for me I was trying to understand the phenomenon of dissolving. Specifically, why does it usually happen that substances usually dissolve faster and more thoroughly in warmer solutions than in cooler solutions? I asked a whole bunch of people about this, up to and including a full professor of physical chemistry, and never got a decent answer.

Electromagnetism Electromagnetism is one of the two forces that dominate our everyday lives (the other one being gravity). The words you are reading radiating from your monitor are a result of electromagnetism, and so is the force that your chair exerts on your body to keep you from falling to the ground (and to the center of the Earth.) The electromagnetic force acts between all particles that have electric charge. It is attractive for oppositely charged particles, and repulsive for particles of the same charge. The electromagnetic force gets weaker and weaker the further apart the particles are, but it's range is infinite. The carrier of this force is the photon, most commonly observed as light. Another thing the electromagnetic force is responsible for is binding atoms together to form molecules. Although most atoms have a net neutral charge, the positive charge from within one atom can attract a negative charge within another atom, thus binding the two atoms together. This is called the "residual electromagnetic force". The next force we will look at is the strong force.

Black Holes and Electromagnetism Abstract: Contents Black Hole Electrodynamics Accretion Disks Black Hole Magnetosphere Flux Freezing ... Disc Field Lines Black Hole Electrodynamics Black hole electrodynamics is the theory of electrodynamics outside a black hole. This is evident since we cannot gain information about anything inside the event horizon (i.e. Black hole electrodynamics can be very trivial if you consider just a black hole described by the three usual parameters: mass, electric charge and angular momentum. Initially simplifying the case by disregarding rotation, we simply get the well known solution of a point charge. This is of course not physically very interesting, since it seems highly unlikely that any black hole (or any celestial body) should not be rotating. Adding rotation then we have to use the Kerr metric with the change that charge is present. This is the Kerr-Newmann geometry where A rotating charged black hole creates a magnetic field around the hole because the inertial frame is dragged around the hole. Far from the black hole at infinity the black hole electric field is that of a point charge, and the magnetic field is a dipole with magnetic moment However, black holes do not even have charges. The ratio of charge to mass, Q/M, cannot exceed

Relativity and Electromagnetism, 16 Lectures, HT by Dr L.J.Mason Aims Maxwell's electromagnetic theory revealed light as an electromagnetic phenomenon. 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

The survey is the result of a giant European Union exercise that polled more than 27,000 people across the continent, 1,375 of them in Britain. It shows that concern about the radiation is far greater than even the most ardent campaigners had dared to believe, and that official attempts to downplay the issue have backfired.

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.
