One 'blind spot' in physics is, despite the fact that it's demonstrable since the 1920s that aligned electron spins cause magnetic fields, this has not been used to explain the magnetic field around a 'current-carrying' wire, as if some other magical mechanism other than aligned electron spins could create a magnetic field.

Hello! Because I have only multimeter, oscilloscope I tried to measure alernate magnetic strength using wire round loop. I asked to ChatGPT - what is the voltage in a loop (250mm diameter) when magnetic strength is 1 A/M and frequency is 2457KHz? The AI told me 96mV.It is a good start point: therefore 2A/M is 192mV e.t.c. When I would develop AC magnetoneter - I would use Fourier Transform, and in according to frequency I would calculated magnetic strength. There may be only etalon loops (for example first for 50-3000Hz, second 3000-50000K, thrid 50K-1Meg, forth 1Meg-5Meg, e.t.c.).When we amplifying and converting analog signal to digital domain - there is very easy calculate amplitudes of each fundamental Fourier transform frequency, and therefore , magnetic strength.
A great introduction to Magnetic Field measurement . Thanks.
Looking forward for your next video about application of this versatile technic 👍👍 great video

Since a magnetic field is produced by electron spins being aligned....
and since a magnetic field instantly manifests around a 'current carrying' wire...
what we really have is this:
- current 'flow' is actually the alignment of electron spins in the wire
- as electron spins align, they lose a degree of freedom of motion
- the latent heat/kinetic energy previously held by the wire/electrons is therefore forced out of the wire because of the loss of degree of freedom of motion - the wire gets warm with current flow
- as the current 'flow' increases, it means a larger number of electron spins are aligning and manifesting a larger magnetic field around the wire, and simultaneously there is an even greater loss in the electrons' degrees of freedom of motion, leading to less ability to carry latent heat/kinetic energy, leading to more heat leaving the wire
- if more current 'flow' is forced by a larger applied voltage, eventually the wire loses a critical amount of latent-heat-carrying ability due to excessive numbers of aligned electrons, and the released heat undermines the crystal lattice and the wire 'burns through'
If you're unaware of how the loss of degrees of freedom of motion of subatomic particles results in a reduction in ability to 'carry' latent heat of the environment, this information is easily found online.
