Hi Manvin, yes, when you have a conductor subject to a changing magnetic flux, the EMF will cause a current in that conductor. In the case of your example, you are correct that a current would be set up in your loop and that this current will generate its own magnetic field. The current...

Generally, particle interactions like collisions should not be thought off as two billiard balls colliding, this is two classical a picture. In particle physics, interactions between protons are usually mediated by photons. Two protons colliding means: they get near enough each other that...

Essentially, this filter violates the second law of thermodynamics by cooling the house and heating up the outside, even if it is already warmer outside than inside the house. This is very similar to a thought experiment known as "Maxwells Demon", as mentioned by Nugatory. Essentially, there is...

Check out Wisp: http://geant4-resources.com/Geant4GUI/G4GUI.html It let's you simulate protons, neutrons, electrons and photons incident an almost any element. Makes a nice 3D visualization too. Wrote it myself, so be nice ;-)

Hi. I guess I am a bit late to the topic, but in case you are still curious here is my input. It looks like kurros is right and they are using Geant4 for the Monte Carlo of the g4numi beamline. (link to pdf), along with a second system called FLUKA. The reason the simulation is called g4numi...
