electromagnetism - How does this "simple" electric train work ...
Aug 8, 2016 · 54 In this YouTube video, a dry cell battery, a wound copper wire and a few magnets (see image below) are being used to create what can be described as "train". It looks …
Finding how to calculate the speed of a magnetic train through a …
Shouldn't that create some sort of repelling force in the middle of the magnetic train? Why would that result in the train travelling to only one side? Then, in the next part, how are we able to …
Energy conservation in Electrodynamics - Physics Stack Exchange
When you say "integral over the space", is it all space? If the "electromagnetic wave-train of finite size propagating in a certain direction" there must be regions of the 'all space' where EM is …
What is the physical process (if any) behind magnetic attraction?
Sep 23, 2011 · If you make a particle "spiral" in the extra dimension. The locally straight spirals give the charged particle motion in an emergent electromagnetic field. Even without the extra …
electromagnetism - Why is the Meissner effect not used for …
May 20, 2015 · Electromagnetic suspension is inherently unstable when used open loop to suspend objects, but by using sensors and feedback controls can be precisely controlled. The …
electromagnetic radiation - Photon energy depends on frequency …
Jan 31, 2018 · I know the energy of a photons depends strictly on its frequency and light is described by electromagnetic waves. Are (single) photons also seen as electromagnetic …

May 29, 2018 · For example, as you have pointed out, it is incorrect to say, "a photon interacts with an electromagnetic field". (2) Imagine a train running on tracks at a constant speed with …
Transverse Magnetic (TM) and Transverse Electric (TE) modes
This is a primary principle that Maxwell discovered. The two always travel together in electromagnetic waves. For example: Where in TM modes the electric field is in the direction …
How would you calculate final velocity for the simple electric train ...
Oct 15, 2018 · 1 Alright, so basically I have an experiment to make, which is similar to the simple train video on youtube. I want to test different voltages & gauges of copper wire to see the …
What produces higher frequency light? - Physics Stack Exchange
Aug 19, 2018 · If you wiggle it a very tiny bit, then you approach the limit where the wave train becomes more like a wave packet, and eventually, a photon. Leaving photons aside for a …
