Deflection coil inside TV, deflects the electron-beam, using magnetic field. However this-deflection is not as simple as electrostatic deflection.
What is the actual mechanism behind working of deflection-yoke coil? I mean in which direction or spatial-arrangement it produce the magnetic fields?
(I searched web for several days, but I could not find anything helpful or clear.)
In web, I found 2 basic mechanisms.

Are they different thing? also,
What are the work of pair of coils marked with arrow? Is it an example of the 1st type ? (appears so from winding direction)
