What IS a field e.g. magnetic field

Click For Summary
A magnetic field is primarily understood through its measurable effects rather than a tangible composition, as it is considered a mathematical entity that describes the interactions between charged particles. The discussion highlights that while classical views suggest a magnetic field arises from moving charges, a static magnet produces a field due to the alignment of electron spins, a phenomenon rooted in quantum mechanics. The origin of magnetic forces remains elusive, with current understanding relying on postulates like the Lorentz force law. Participants express confusion over the physical reality of fields, questioning whether they exist independently or are merely mathematical constructs. Ultimately, the nature of magnetic fields and their underlying mechanisms continue to provoke inquiry and debate within the scientific community.

That is totally unfair! What makes you think that I'm not trying to expand my knowledge as well as that of mankind?...

First, let me say I was not directing my comment to you personally, but to anyone who thinks we need to stop reaching farther than the doctrines we are fed.

I have a hard time believing the large research facilities would be the only ones that have a chance discovering these primal forces than anyone with some basic skills and a thinking brain. Choosing to continue with your education after all these years is a good indicator that you are still searching for answers. Maybe you will be the one to discover something previously unknown someday.
Remember Michael Faraday? He was just a blacksmith who was an avid reader and dabbled in experiments.
