Homework Equations
The Attempt at a Solution
I have to idea as to how I should proceed!
graphene said:There is no simple explanation. You will have to look into quantum electrodynamics.
PiTHON said:Would the answer be "because there is a changing electric field"?
hasan_researc said:Why?
graphene said:Yes, but the question was why, "why does a current produce a magnetic field" ?
We give below the full list of transformations. All primed quantities are measured in the frame F', which is moving the positive x direction with speed v as seen from F. Unprimed quantities are the numbers which are the results of measurements in F. As usual, \beta stands for \tfrac{v}{c} and \gamma for \frac{1}{\sqrt{1-\beta ^2}}
