Interesting Video On Electricity

Interesting video I found on how electricity works.

The electric and magnetic fields inside and outside the wire require no medium to propagate

The EM field is OUTSIDE the conductor
A very small electric field is inside the wire ... the main electric field is outside the wire

yup, a good video ... a couple of little omissions but overall very good for the general public

Got me thinking there. As far as I understand.. the field is zero at all points inside the conductor. I don't know if that means the field does not exist inside the conductor, or whether it does technically exist yet at some variant of null..

I'm still amazed that the EM field requires no medium to propagate.. took me years to find a way to visualise that it does just that.

I'm pretty much the gen pub & did enjoy the vid

Almost 25 years ago, I enjoyed this explanation I just searched again in order to submit this post, is still present on the web :

Am happy it is still available. There is many branches in the subject, abundant links within the tutorial, each one surprising. Explore those embedded links within the text and be prepared for an overdose !

Many misconceptions that teach things the wrong way since lesson one. And no institution reforms it to a scientific consensus.
