Basic Electricity & Magnetism Lecture Part 1.mp4

[@cheyennebrunner7757]

My husband was recommended to your channel, he and I are starting a fun journey down a wild road! Thanks for having us.

Great job. I just can't get my head around Electro-magnetism, but your presentation is beginning to penetrate my thick brain. Thanks again.

It is questionable to discuss atomic activity at that level in a short discussion on basic electricity. It is sufficient to point out that "they" believe they know the cause of magnetic polarity. I think I made it plain that this was a cursory, 10,000 foot view on this subject. It is a representation and not a warranty of the most current THEORY, emphasis on THEORY. I needed the polarity of the electrons to give the field polarity when the electrons are moving in one general direction.

This is brilliant, I just wish some of my teachers had put the same amount of effort into their subjects when I was back at school. Please keep posting, I'm sure many people benefit from these tutorials.

Great lecture. Your videos have been very helpful. Many thanks for your knowledge and effort to help and educate others including myself.

43:30 this part should have been better explained. Why the induced current started to move to the left (i.e. the electrons started to move to the right) when the external magnetic field is getting denser. Do moving electrons (magnets themselves) move their north poles first in the wire? Magnetic field generated by the current has its force lines pointing in the same direction as the external magnetic field, ie in the beginning the loop has its north at the bottom? Why? 43:44 detto when the loop start to turn

Very clean and insightful presentation. Thank you very much. Keep up the good work

Beautiful video! Thank you for sharing your knowledge.

[@JBAudio]

This was a very thorough and easy to follow lecture. Thanks!

[@mustseewhentraveling1577]

Thank you professor. With animations and pictures the lecture is very easy to follow.

Thank you very much for your presentation. It was very easy to follow and well explained ^.^

[@patrickkorir9149]

like your lecture so nice

Thank you for this video! I did have a question-- usually the armature in a solenoid is just some ferrous material, so that once current flows through the coil, the dipoles can line up to where the center of the coil attracts the material to an equilibrium state. Could there be an instance where if a permanent magnet was used as the armature, the poles on the magnet were aligned in such a way that the solenoid would reject the metal as opposed to attract it to its center? I am thinking that it would depend on the direction of flux of the coil (from the right hand rule) and the orientation of the permanent magnet. Am I understanding this correctly?

[@plcprofessor]

Correct...Once the coil is energized, it becomes a weak magnet and its interaction with a permanent magnet is the same as if it were a weak permanent magnet, toroidal in shape with the poles existing on the axis of the hole.

Thank you very much!

Thank you! Ive been trying to work on a magnetism STEM project, so this really helped :D Keep the good work!

[@plcprofessor]

magnetism STEM project... you have my interest!

[@usedtogiveadamnbutnevergav1960]

:D

I have seen this example before and it is NOT an optical image to the eye by means of reflected light or illumination. Disturbing matter with energy and recording the energy given off is not "seeing". Scientific value, yes of course, but this not direct observation with the human eye, seeing. Using the verb "see" as a substitute for "understand" is an incorrect use of the word. As a matter of fact, looking at a photograph of an object is not "seeing" the object. "Seen of" is not "seen it".

[@bunnandjenn9405]

Thanks for the video

[@dougpine4746]

Nice presentation.

[@plcprofessor]

I do have texts on EMH and I have read them. Today the subject is basic electricity, not quantum mechanics.

[@electriciandallastx9182]

Thanks for the thoughts you have shared here.

[@plcprofessor]

Actually, no one knows the underlying "physical structure" of magnetism, gravity or electromagnetic energy. It is all empirical speculation based on several popular models. Electrons as we think of them are components of the Bohr model of the atom. The polarity is thought to be the product of the direction of rotation. No one has ever "visually seen" an atom much less electrons or any other sub components. It serves us well to always keep in mind that any notion of that not seen is speculative.

Los croatas y alemanes son los más grandes, y franceses, ahora le toca a los latinos

[@aashishrawal1794]

that is not mandeleev periodic table. it has got lanthanides and actinides.

Thank you for this vedic
