Obviously, it's 42. Thanks Vanadium 50, and everyone. I'm going to dig into my physics books to learn more about magnetism, and do some experiments to get the hands on understanding of what is really going on with fields and forces. Just when I thought I knew something I find that my ignorance...

Thanks. No mass, no magnetic interaction. That caused a flicker of light in my brain. Magnetic fields can be deflected, but the fields themselves cannot be imaged, because imaging requires light. Well, it requires light, or sound, or some type of radiant energy, and a receiving medium to catch...

The lines represented by iron filings on a magnet look real enough.

Sorry about my reply format ignorance. I don't use this board very often.

Thanks. Nice to have pictures of what I'm talking about.

Magnetic fields are real physical things. They are not imaginary.

They are a human construct. They are not physical things.

The charge between two plates in a condenser can be measured but not photographed in any way. I get that. Lat and long are a human construct. Even though the EM field does not emit or reflect light it is physically there. Eyes cannot see without light, but with light things are seen. I think the...

First astrophotography was black and white. So then we colored it in. Then the light got filtered so people can see the universe better. When I ask why are there no photographs of magnetic field lines in space, or anywhere; I read that it's because our eyes cannot see them, but we can't see...

If I flip two coins should I expect to see the probability wave? I don't know. (A real question.) Or are the experimental results like fluid dynamics, where the wave would be expected to draw an interference pattern having moved forward through the two slits. Yet, it looks to me like the...

The electron's electromagnetic field interacts with other waves, and maybe in this case it is running perpendicular to the Earth's magnetic field. With a group of electrons, although you can see an interference pattern, I don't understand how it can be inferred that an/the electron has...

What I've seen of the experiment involves sending a stream of particles through the slits. I'm extrapolating when I say that the interference pattern could be caused by electromagnetic fields (in the case of massive particles), especially because the particles are moving and probably spinning as...
