That is one of the reasons we can type here. Magnetic fields that can be detected at any considerable distance from their source are due to magnetic domains that are lined up preferentially in the same direction...

The fields around the many atoms are oriented in random directions and the sum of them cancels and is essentially not detectable at any great distance.

I was trained as a physicist. That is the background for my orientation on the matter. Any idea that there are actual physical fields around people that can be detected by other people near them is one of those new-age ideas created by people who want to believe in something, not by people who actually know anything. If you disagree, find me scientific evidence for the existence of those fields (not something created in Photoshop) and detected by people by unaided sensory means.

The existence of such physical fields is not needed to explain how people with regular sense perceptions can understand things about other people by seeing and hearing their actions and words...

That is my unkind dogmatic stance for today (unless I see other posts that I feel the need to reply to in a similar dogmatic way).
