Physics, Astronomy & Cosmology / Re: What makes a magnet a magnet?
« on: 30/09/2016 04:35:13 »Most magnetism has to do with the "spin" of subatomic particles.
My thoughts also...
As a graduate lecturer and overall science peep for too many years, your answer was a reflection of my thoughts..Particularly the (electron) spin component with a dab of good ole' E-D-Haas angular momentum effect for fun.
I hope this Q has not been asked repeatedly, for I did not do a lot of digging...

Physics, Astronomy & Cosmology / Re: Do waveforms beyond the visible spectrum form rainbows?
« on: 30/09/2016 03:04:54 »
I believe evan is right.
Nonetheless it is a good question.
If I understand your Q correctly, visible light is is simply a "slice" of the RF spectrum. Therefore, if we could expand our bandwidth via mechanical manipulation or the size, depth, and/or chemistry of our eyes like tuning a radio receiver to a different channel we would see below and above the visible spectrum like some critters do.
You see, visible light is just a piece of the "larger same"....a magnetic and electric field generally perpendicular and travels at c in the same medium through the same index of reflection, etc.
I would suggest to my students when trying to figure out the answer to a continuum question like this is to frame it relative to both extremes which would be DC and a freq so high that the wavelength might be a short as the diameter of a hydrogen atom or smaller..
Always take mathamatical based inquires to the extremes for ease of reasoning!
This method saves time and heartache for many students, for many decades.
2nd Q:, "Do all the wavelengths form stripes like visible light does"?
Technically yes they do. play around with a spectrum analyzer.
Cheers!

Physics, Astronomy & Cosmology / What makes a magnet a magnet?
« on: 30/09/2016 02:29:01 »
I don't want answers like..."a magnet is magnetic bc it is metal or ferrous", or "magnets are magnets because they have 2 poles"..
Do we really know? IE: light can be suggested in the lab, that it has wave and particle properties..Hence the term duality.
Soooo. what makes a magnet, magnetic?
