Waveform of pulsed magnetic fields...
I have recently been astoundingly interested in magnetic fields, for seemingly no reason. The point is, that in reading up on it, and being a big fan of the greatest mind of all time, Nikola Tesla, I have been stumped with a question that I can't quite seem to answer, and can barely wrap my head around. My question is this; when one takes a normal electromagnet and sends pulses through it, is the resulting pulsing field considered to be longitudinal or transverse waves, or something else all together? This has baffled me, and I am curious to see the answer. Another question I have is, what exactly does Tesla mean by "hertzian" waves, I'm assuming that that his "non-hertzian" waves are longitudinal waves, but I could be wrong.
A little background on the question... This question arose when I was looking at the 'ible "spooky tesla spirit radio" (something along those lines, I'm not sure the exact name). I read somewhere in the comments section that Tesla found Hertzian waves to be, for lack of a better term, a waste of time. This brought the question of different waves up, and one thing led to another and here we are!!
Thanks for any and all answers!!
