Regarding the Lorentz force:
I know that the Lorentz Force law states that:
$\vec{F} = q\vec{E}+q\vec{v} \times \vec{B}$
And then for the magnitude of the force, where $q_2$ is the moving charge:
$E = F/q_2$, and therefore $E =...

Direction of magnetic field lines around a conducting wire
By way of the first uploaded picture I was taught that magnetic field-lines around a long conducting wire with a current are shaped like concentric circles around the wire. However, a few pages ...

About fundamental physics (static fields, forces, and energy)
Disclaimer, so that you can provide a more informative answers: I have a degree in mathematics but I am quite ignorant in physics.
I was reflecting about the ability of a charged particle (any ...

Using newton's third law in electromagnetism and special relativity problems
I am confused with using newton's third law in electromagnetism problems which includes Lorentz transformation.
In what conditions does this law holds?
for example, if there is an infinite charged ...

What is the *cause* of the Lorentz Force
Is it possible to explain what actually causes the force on a current carrying conductor in a magnetic field. I have read that this is due to the magnetic fields 'interacting' in some way.
This ...

Are the field lines the same as the trajectories of a particle with initial velocity zero?
Is it true that the field lines of an electric field are identical to the trajectories of a charged particle with initial velocity zero? If so, how can one prove it?
The claim is from a german ...
