### relativity in an electron beam [duplicate]

If two electrons are travelling side by side with the same velocity with respect to me, they are standing still with respect to each other. For me, they will exert on each other an electrostatic force ...

### Is there a magnetic attraction between two parallel electron beams?

I am refering to Ampere's force law, and to the beams accelerated after the cathode, so the deflection is not due to their respective cathode. In other words, do two electrons accelerating parallel to ...

### Force between two point charges moving parallel to each other

When we observe two point charges moving parallel to each other we can see two forces acting on each of the charges: the Coulomb force the magnetic force ($\mathbf{F}=q\mathbf{v}×\mathbf{B}$) (...

### Relativistic electromagnetism and electromagnetic forces on 2 protons

The question I have about it is how we can get the same result of net force acting on the individual protons if we judge the system from 2 different reference frames. One using more of the magnetic ...

### Is Magnetic force really the relativistic correction for electrostatic force?

Imagine two charges (aligned vertically) with a separation $r$ in a spaceship moving with a velocity $v$ with respect to earth. In the spaceship frame, the charges are stationary with a force F′=\...

### Would Magnetic field be Zero if measured while moving along with charges?

According to Einstein's relativistic interpretation magnetic field caused by charges moving inside a wire is caused only by the relative speed between charges and the observer. So, if electrons are ...

### Do two cathode rays attract each other?

We know that two wires carrying current in the same direction attract each other and there is a well know explanation for that. I am just curious to know if anyone has ever seen any experiment where ...
