electromagnetism - Does a classic physics describes the electric charges forces propagation speed?


When you launch this applet you can notice, that in the beginning the force lines are propagating from a charge, with some speed(speed of light, probably).


The force lines means, that in every point of the space there are force with straight-defined direction, according to charge position. When charge is changing it's position, the force direction and density should change too.


So, how does a classic physics describes the electric charges forces propagation speed?

classical mechanics - Moment of a force about a given axis (Torque) - Scalar or vectorial?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
