Has anyone ever wondered whether the phrase "putting two heads together" could actually be possible?

To build on what I'm trying to suggest I'd like to first set down the basis of what I'm talking about here.

The human nervous system is basically an electromagnetic network of electrical impulses and signals being transmitted and received in the blink of an eye. Charges by themselves produce a corresponding electric field in their vicinity. Furthermore, moving charges cause a change in electric field, which manifests as the resulting magnetic field.

When you think, perceive, feel, do or imagine; your nerves, neurons are buzzing with electromagnetic activity.

All fields follow the superposition principle - that when two or more fields overlap, their vector sum is the resultant field.

So consider two people thinking or concentrating on the same thing. If you already see what I'm driving at, hold your doubts. When both think of the same thing along the same lines, their brains will produce a particular magnetic field, unique to the thought process. If both their fields overlap, they would double the resulting field around their heads, and this in turn would for sure affect their thinking capacity. Experiments do in fact suggest that an external magnetic field affects brain function noticeably.

The problem with this idea is that the fields so produced are extraordinarily weak, and their strength is so negligible beyond a centimeter or two that they can't even be detected, for the earth too has its own magnetic field, even if very weak. (You might guess that the idea that you should sleep in a particular direction makes some sense in this light, and might not be absolute quack-talk.)
