prime quantity การใช้

Where the primed quantities are the charges and fields before the transformation, and the unprimed quantities are after the transformation.
Unprimed quantities correspond to the rest frame of the magnet, while primed quantities correspond to the rest frame of the conductor.
The transformations are applied to take the velocity of the frame from the velocity of each particle from the lab frame ( unprimed quantities ) to the COM frame ( primed quantities ):
Unprimed quantities refer to position, velocity and acceleration in one frame F; primed quantities refer to position, velocity and acceleration in another frame F'moving at translational velocity "'V "'or angular velocity "'? "'relative to F . Conversely F moves at velocity ( "'V "'or "'? "') relative to F '.
