How Can You Reproduce and Understand the Meissner Effect Experiment?

Click For Summary
The discussion focuses on reproducing the Meissner effect experiment, highlighting the importance of understanding the theoretical foundations behind it. Key experiments include a demonstration using a type II superconductor and liquid nitrogen, with references to classic superconducting magnet experiments. Participants suggest starting with Wikipedia links for foundational concepts and mention the availability of "Meissner kits" that include YBCO superconductors and magnets. Liquid nitrogen is noted as an accessible resource for conducting the experiments. Overall, the conversation emphasizes practical steps and resources for successfully replicating the Meissner effect.

It would be helpful for you to provide some basic description of the content. Links to Youtube are too often the source of "joke" videos.
 
Well, one was the classic superconducting magnet experiment, the other a plasma light (think: neon sign), so start with the Wik links for those two concepts.
 
The first experiment is -as russ watters has already pointed out- just a demonstration of the Meissner effect using a type II superconductor (albeit without a spacer, they must have repeated the experiment a few times before they managed that, I am rarely that lucky), the liquid they are pouring in the white cup in the video is liquid nitrogen.
You can quite buy "Meissner kits" that consists of a piece of YBCO superconductor (the black block in the video) and a strong permanent magnet. Then all you need is some liquid nitrogen which is usually fairly easy to get hold of. You can buy these kits from e.g. Can Superconductors.
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
