You are a first rate teacher. You deliver content in such an easy to digest manner, engagingly, and in the end I find you've slyly lead us through understanding the mathematical proofs for the theory too.
I can't thank you enough for uploading these, not only you explain everything clearly but you actually make it entertaining to watch. I have a test on this tomorrow and you basically saved me (yet again)
Don't worry, I understood your Divo, VHS and cassette tapes! Haha. Can't decide if that's making me feel old yet or not that people don't know about those anymore... Thanks for another great video again Professor!
The actual output from a mass spec is given in atomic mass units (AMU). You get a graph with AMU along the x-axis with a series of vertical lines at various AMU representing the abundance of that particular mass. The analysis of a mass spectrum can be quite complicated depending on what you are analyzing. Complex organic molecules yield complex spectra. Upon ionization, the molecules break down into fragments, the mass spec yields the abundance of the masses of each of those fragments. Those masses, their relative abundances, and knowledge of how molecules break apart are used to determine the structure of the original molecule. Okay, for the sake of honesty, we would use one or more of the following in conjunction with the mass spec, IR spectra, visible spectra, UV spectra, and NMR . But, the mass spec yields important information on the masses and abundance of the various fragments. Wayne Adams B.S Chemistry (ACS Certified) M.S. Physics R&D Chemist 9 yrs.

Yasir., No, the thermal agitation knocks them out of alignment. Good discussion here: hyperphysics.phy-astr.gsu.edu/hbase/Solids/ferro.html Thanks for the comment, and keep up with the physics! You might also like my new website: www.universityphysics.education Cheers, Dr. A
I've never studied, but physics is a great interest. Thank you for sharing this. I have some difficulty seeing EM as one force. Our galaxy has a magnetic field, like it has gravitational field, but not an electric field? An electron has negative electric charge and a magnetic field, but there's no particle with a monopole? They don't seem similar at extreme scales.
Great questions. I should point out that our two greatest theories: quantum (small scale) and general relativity (large scale) have yet to be reconciled. Cheers, Dr. A
Thank you I asked about 5 months ago for this. Thankyou for showing me how humans being a magnetic field increases their magnetic fields by bring closer to other human brings with math. I am a solenoid. Erupting love, hope, joy, and gratitude within the hearts of all mankind. These frequencies are between 500 to 600 hertz. A group has increase the heat on the earth. To restructure the information on earth how many coils to we need? Application I must find a way to create those coils.
Why are the plexiglass text and diagrams oriented the normal way but the title of the 'Caddyshack' VHS is flipped right-to-left? If the video had been altered to make sense for the camera (online viewers), wouldn't that mean it would be reversed for the student audience? Unless they are seated behind the professor?

I have a question about the B field outside a solonoid. If there is a B field around a current through a straight wire why isn't there a B field at the outside when this wire gets wrapped around some coil. I would have thought the outside path has a value of -BL?
jos, There is, but we approximate it as negligible compared to the field inside the solenoid. Thanks for the comment, and keep up with the physics! You might also like my new website: www.universityphysics.education Cheers, Dr. A
@@yoprofmatt Thanks, now it fits in my mind that B lines are continuous having beginning nor end and are only squeezed inside the coil as on the outside they have the whole universe to expand.
S Menezes, Excellent point. There is, of course, magnetic field outside as well, but it is so much smaller that we approximate it as zero. Thanks for the comment, and keep up with the physics! You might also like my new website: www.universityphysics.education Cheers, Dr. A
@@yoprofmatt Teaching middle schoolers for Sci Olympiad, I told them that for a wire conductor, the field strength around it B = u * I / (2*pi*R). So, closer R is to the wire, greater the value of B. Does this not apply to a solenoid due to geometry?

Thanks for giving me some confidence in the world of electricity.
I liked that you have explained how a tape cassette works and how it is related to the magnetic field. Thanks!

Which chemicals are used to make magnetic oil
That sounded like a norm macdonald joke in the start, but I am not sure.
At 35:13 shouldn’t increasing the temp of the iron bar increase its energy and thereby make the spins “more” aligned?

At 20, why is there no B field outside the solenoid? It should have a magnitude because magnetic lines are in a continuous loop.

Just a small nitpick: you said "42 centimeters which is 0.42 meters in SI units". Well, centimeter is still an SI unit, it's just not a _basic_ unit.
