    Useless video.

    the right hand rule also called screw rule is a three dimension rule (x,y,z), so having the hand just quiet as she does cannot show anything. What she explains in fact can be done with the left hand as well.

    notice her eyes are slightly shifting upperleft side. she is reading the script, don't feel bad when you couldn't catch up with the density of information about induction...

    If anyone reads this comment first before watching: you need to have some background knowledge. They barely anchor this knowledge down with practical examples

    They love to talk fast when there's sleight of hand going on. Wipe-worthy propaganda paid for by people who are looking out for your best interests and not theirs solely. A public voice being provided to by the corporations that provide one way thought.

    I believe at 2:55 you said that if the angle from the perpendicular normal to the loop and the field are perpendicular then the flux will be max, however its when they are parallel, correct me if im wrong

      Wow, your school sucks. Just saying. What school is it? Not AZU I hope because I get free tuition there and was planning to sign up for EE.

    Thank you for your work👍. It seems pretty fast and no time for thinking to thoroughly understand well such a technical things unless the guy was very well in this aspect. Anyway thank you again for trying made it simply for me to understand😁

    If I get this right, a coil must resist every change in current since the "neighbor wire" (the same wire, but a different turn) induces a current in the opposite direction. It seems to me like there should be an energy loss any time you use a coil. Is that right?

  • Barmherzig sein

    This is not a lecture (i..e. Not a purposeful attempt to a) convey knowledge previously proven via consistent outcomes in real life/everyday applications, AND b) explain said information via the utilisation of several practical descriptive examples of and/or several practical physical applications of the information covered by that lecture). Instead, this young lady, who seems to be quite knowledgeable regarding the topic of this presentation, is simply reciting information. Although I am familiar with the topic of EM Induction, usw, usf... I found this presentation to be uninteresting and reminiscent of a lecture on speed-reading. Sadly, these issues are not uncommon in the field of online „education”.
    Thank you for allowing me to share these opinions and perspective on your channel. May you live in peace. Salome.

    I properly pause this video 100x to take notes in order to really understand the concepts. 10 mins crash course more like an hour in half crash course.
