Force on charged particle when moving along magnetic field lines
I was thinking, what happens to the force on a charged particle when it is moving along the magnetic field lines?
I am familiar with the right-hand-rule and it seems to me that RHR does not apply in ...

Can every mass obey the Newton's 3rd law?
As in, if we were able to produce a very huge amount of force on a very small body, would it push back with the same force? Given it doesn't break or disintegrate.
Like if we electromagnetically put ...

How can Laplace (Lorentz force) move objects (and not charges)?
Hellow everyone,
I got this question that has been teasing me for a while now :
I see how Lorentz force can act on a "free" moving (in a magnetic + electric field) charge, however, it is difficult ...

Why does linear motion not affect the reading on a hall probe?
Moving the hall probe forward at velocity v would make all the electrons in it propel at velocity v, so the magnetic force on each electron (qV x B ) would increase. If so, unless there's some fuzzy ...

Work done by magnetic force
By Lorentz force law, $F_m$ is always perpendicular to velocity of charge $v$. But $F_m$ is not necessarily perpendicular to the displacement of charge caused by $F_m$ .
Then how can we say that ...

Why does the axle need to be rotated in a turbine generator?
Inside a turbine a wire rotates between the poles of a magnet, i.e. rotating inside the magnetic field, so that the field forces the electrons in the wire to move and generate current. But why does ...

Foucault currents with a simple pendulum
I have this diagram :
It's a kind of pendulum; when it swings, it passes through a small aera where there is a magnetic field. Therefore, the electrons moves towards the bottom because of a Lorentz ...
