11. Lord Kelvin's Mirror Galvanometer

Gosh, I wonder when that movie was shot?

Two of the greatest minds ever, Thompson and Maxwell. Good appreciation of their work. I like the gloves used respect instruments that were the beautifully built tools used to teach in a classroom. The length of the light-ray "arm" of the instrument shining from a vacuum chamber , can easily be made so long that, in the absence of current in the coils the vibrations from the mount caused by distant earth tremors provide a commentary of the dynamic nature of our environment.

Wonderful presentation. Information and artfully done. Thank you.

Good Morning. I am a graduate student in the Physics Institute of the Federal University of Rio de Janeiro (IF-UFRJ), Brazil. I'm building a galvanometer or Kelvin mirror galvanometer for use in the classroom. I found few digrams and photos from the internal construction of galvaômentro. I ask if they had some internal picture or diagram to help me. I appreciate the attention. Any help will be properly cited in the references.

You obviously knows your stuff but you're not a good teacher. You failed to mention the very basic fact of how the mirror achieve it's angular variation so that the observer could read values off the scale. A very very basic thing you'd have mentioned!!
