    Magnetic Field in a moving Medium

    I was hoping there might have been a magnetic field test when the steel is stationary and when it was moving. The same concept might apply to a material with a high dielectric constant moving at high speeds, and the electric field be effected on the other end of the material. i will try...

    Magnetic Field in a moving Medium

    I recently learned about the Fizeau experiment, http://en.wikipedia.org/wiki/Fizeau_experiment"]http://en.wikipedia.org/wiki/Fizeau_experiment[/PLAIN] showing that light moves with a moving medium to an extent. However i was wondering what would happen with a magnetic field in a moving...

    Magnetic and Electric Fields in Gravity

    electromagnetic radiation comes from an accelerating electric charge. it is the acceleration of the charge that emits photons. It is different from an electric field from a stationary charge.

    Magnetic and Electric Fields in Gravity

    ok thanks for responses, i was curious about whether light actually created its own gravitational field. As for magnetic and electric fields, i know it takes energy to create them, so i am guessing this would have to cause a mass increase in the object containing the field. so there is no...

    Light Passing through a Moving Medium

    I was looking at light sources Bending in Accelerating objects from this astronomy page http://www.astronomynotes.com/relativity/s3.htm" Then i began to wonder if this moving elevator was made of glass then the light would hit the glass and "move slower". Then if the glass was moving i was...

    Magnetic and Electric Fields in Gravity

    Is there any effects on electric fields or magnetic fields in a Gravitational field? I know that electro-magnetic waves(photons) are effected from the bending of space and time, from gravity. however i was just wondering how magnetic fields or virtual photons respond to gravity. Any...

    Moving Electric Charge Creating a Magnetic Field

    the problem i face with Biot-Savart law and briefly looking at Jefimenko's equations from wikipedia. http://en.wikipedia.org/wiki/Biot%E2%80%93Savart_law" is finding the current or current density of a small charge such as an electron, or a point charge based on its velocity. The way i...

    Moving Electric Charge Creating a Magnetic Field

    Ok, i think i have a better understanding of the concepts, though i don't really understand all of those formulas. If i were to keep it simple and just consider two moving point charges with the same charge and velocity. would the forces be? Electric Force Fe=k(q1 x q2)/d2 Magnetic...

    Lorentz Contraction Circular Motion

    Does Acceleration affect Lorentz contraction? Suppose their was a Circle spinning around its center then its outer edges would decrease in length. looking somewhat similar to a saw blade or something. This doesn't make sense though because then then object would change shape depending...

    Moving Electric Charge Creating a Magnetic Field

    Does a moving charge create a magnetic field? At first the answer was obvious to me, since I = Q/t then if a charge is moved it is simillar to an electric current, and electric currents create magnetic fields. However in a conductor, an electric current consists of electrons moving past...
