Thank you all for y our comments re the possible interactivity of two like
fields. I am a bit mystified by the responses -- the following seems to
be somewhat typical:
| Sounds imprecise, but not wrong. Force fields interact in the sense
| that they are vector fields, so electric fields add like vectors at
| any given point in space. Thus, electric fields from multiple sources
| can reinforce or cancel each other at any given point in space.
Well yes, but suppose that there are three stationary electrons nearby each
other. I can calculate the electric field due to each of them, but if I
want to find the net force on electron I calculate the fields due to B &
C, add them vectorially and then treat the result as ONE field.
But I need to remember that the various fields do not really exist -- they
are _inventions_ -- mathematical constructs if you will -- they are not
fluids which "interact".
Now, dear gurus, can we get some additional comments???
