ME? the coil generates an M which induces localized E in the body as shown by localized currents? (which produce some more M, but only just enough)
- dekhn 2y agoI can't parse what you are saying, but there's a difference between EM radiation and a magnetic field (and the resulting locally induced currents). Think in terms of an MRI machine: it puts you in a giant magnet (causing the various nuclear spins to align with the field) and then sends a bunch of EM radiation (radiofrequency). The former is a magnetic field, not EM radiation.
- fsckboy 2y agoit's all E x B, just different functions for E and B
- neutronicus 2y agoOP is making a distinction between "EM Radiation" (i.e. "light") and "Quasistatic fields". This is warranted because they are pretty different - light has a frequency distribution, diffracts, etc, and can be focused to propagate energy over distances large compared to its source, whereas quasistatic fields (by definition) have no frequency distribution, and die as 1/r^2 or faster
