One thing I have noticed....all the Khan academy teachers have that positive vibes emanating.

of course your teachers tried, but factors like interest and distraction and comm skills may have been a challenge. To be fair with teachers, they had to deal with students year after year after year making the same lessons you teach year after year boring to you and this also makes it boring for the listener or the learners. School may not be the most efficient way to educate, but at least there you can make mistakes and not lose your job or your life as opposed to trainings and practical applications while working completely ignorant of what is going on. And because you already have an earlier experience with such lesson even if you don't understand it much back then, all the job trainer had to do is reinforce the context that was already there and fill in the missing info to make it cohesive with all the other info that is retained in your memory, making the idea clearer to you. And this reduces the risks of human error. Experience or encounter with contexts, lessons and ideas earlier in life which is then recently reinforced by filling all the missing info later on in life, is a rather more effective way of learning as compared to studying contexts, ideas and lessons that are totally alien, foreign or brand new to you. And this is why having gone to school remains our standard way of professional life.

[@gurlalbrar1236]

Seriously, no words to describe. Animation and explaination both were awesome. I haven't just think about wireless charging is done by this method. ........ Unbeatable 🔥🔥🔥🔥

I have a doubt If the change of magnetic flux generated can produce the same amount of emf in another coil(secondary) Then wont the change of magnetic flux induce the emf in itself(primary coil) and affect the flow of current in it?
