  My second video of yours to watch and it answered some questions I had about transformer gaps. Thank you very much for your knowledge.

  I did some review on my basic knowledge on magnetics recently related to a job issue related with changing voltage requirements in some inductive components. After some hard work of remembering why things work in all this stuff, of N, L, voltages permeabilities and whistles, I wish I had seen this lecture before. It is clear when somebody master the topic and how to explain it, you don´t need fancy animations, but a whiteboard and a clear understanding. Will save the channel for other videos.<br>I think flux formulae for V= &nbsp;A sin (wt) should be -(A/w) cos (wt), has no effect on the discussion, but just in case..

  I absolutely love your videos. You had a significant effect on my degree, and you are continuing to help now I am working as a power engineer. The work I do pushes HV technology to overcome the use of herbicides in agriculture, so looking after the planet. Thank you Sir - from the UK

  I have looked at your video about HF transformers. These videos are really helpful but when designing or calculation part, units of elements(B--&gt;Tesla or mT, Ae--&gt; mm^2 or cm^2) do not exist. If you can, please share these units with us in the comments. Thanks for your lecturing.

  thank you for the valuebale informations that you are proviing us with, i have a question how can you find the number of turns/b max of a transformer from the nameplate ?

  Hi Professor, on page 9 [<a href="https://www.youtube.com/watch?v=C4TWJbcDCCw&amp;t=865">14:25</a>] you mentioned that shorted output will not cause the core to operate in the saturation while large input current is induced. However, under this circumstance the input voltage is still AC with very large AC current as well. Is that possible when exceeding a certain threshold of input current, this would bring the core into the saturation?
