Since photons have rest mass zero, and correspondingly travel in the vacuum ... The basic idea was that in QFT the electromagnetic field should be ...


Since magnetic field lines are just constructs the field cannot contain energy? ... A magnetic field line can be thought of as consisting of lines of force. The forces ...


Since electric field is a vector quantity, it can be represented by a vector arrow ... Not only does the density of lines surrounding any given object reveal ... Consequently, the lines representing the field cannot cross each other at any given location in space ... But what if a region of space contains more than one point charge?


Apr 12, 2012 ... The term Dark Energy confuses the issue, since it isn't (just) energy after all. ... All particles are ripples in fields and have energy; photons are not .... you can't have an elementary particle without a field, but you can have a ..... But no one has any practical reason to try to construct large amounts of anti-matter.


An object that contains Fe is not by itself magnetized, it can be attracted by either the north ... You can draw magnetic field lines just like you drew electric field lines . .... Magnetic force perpendicular to v → it cannot change the ... Bainbridge was able to construct a device that ... After this, in the region of B' particles with m. 2. >.
