What is the force between two charges moving at 0.5c relative to each other? [closed]
Suppose two charges, $q_{1}$ and $q_{2}$ are in uniform translational motion relative to each other. If the relativity velocity is relativistic, e.g. $0.5c$, how can the force between the two charges ...

Where does force act in two parallel current carrying conductors?
F=ILB.so consider length as 5 m and I as 2 ampere and B as 5 T.so the force is 50 N.does this 50 N act at one point or equally applied on full length like pressure.So what does force/length in this ...

Is the magnetic Lorentz force $\vec{F} = q(\vec{v}\times\vec{B})$ a force of constraint?
I am currently studying the Lagrangian mechanics, and as far as I've understood, forces of constraint are the forces that are perpendicular to the surface of the movement of the object, thus do not ...

Can the following set up be used to propel something upwards?
Let A and B be solenoids with the same pole facing each other.
Then will their repulsion cause the set up to jump upwards?
Please correct me if I am wrong:
Solenoid A exerts a downward force on ...

How do you calculate the force between an electromagnet and a piece of iron? [closed]
I am building a simple electromagnet, with an Iron core, and want to calculate the force it can exert on another piece of Iron when in direct contact with it (Basically how much weight it can lift). ...

Where does the Force on an Electron Come From?
The interaction (of an electron with an external electromagnetic field) is because of the electron's charge, but charge causes an electric field, so, by Syllogism one can say the interaction is ...

Time lag for generation of electrostatic force
Suppose we make a certain point in space charged. Say we impart some negative charge, such that electrostatic condition is maintained.
Then, after the point gets charged will the electric field due to ...

Can a current carrying loop experience force due to its own magnetic field?
In my opinion, the wire must expand due to the magnetic force acting radially outwards on two diametrically opposite ends of the loop as a result of the equation:
F = I(dl × B)
Where B is the ...

Poincaré inverse square law unification
A while back, I came across a claim that was something like this: Poincaré said that no two fundamental force laws could have the same mathematical form such as $1/R^2$; that no two fundamental force ...
