Magnetic field of 1 Tesla

https://www.researchgate.net/post/How-do-i-produce-a-magnetic-field-of-1-Tesla-for-magnetoelectric-measurements David Coathup   Did you ever get your magnet working? I am writing notes on magnetic calculations and your 1 Tesla magnet is a good problem. This morning I found a good example in “Electromagnetics” by John D Kraus and Keith R Carver, 2nd Edition 1973, page 250. They cover magnetization in the previous

Comment on Video Demonstrating Convection, and approaches to understanding and visualizing

How to demonstrate convection at https://www.youtube.com/watch?v=-8PoCwx2de0 The simple materials are good, but you, yourself, did not explain what you were expecting, where the students and demonstrators were supposed to focus their attention. You said (don’t use purple shirt) and for this short video, why did you not go change your shirt and record it again? Or,

Comment on Making Petrified Lightning – application to solar system colonization, global needs and new industries

TheBackyardScientist,  Making Petrified Lightning …with electricity? at https://www.youtube.com/watch?v=m7YznIKe7bU 3D printing metal. You can use metal or glass powders, control the current, and randomly choose next points – probably run on Arduino. You have all the skills and stuff mostly. Maybe someone already suggested. You might invent a way for YouTube viewers to work together, combine

Comment on changing torsion bars to controlled shock absorbers – value of measurement and simulations

I Deleted My Tahoe’s Torsion Bars for Something Much Better at https://www.youtube.com/watch?v=fOyuvd5epFg There are apps for your cell phone that record the data from the three axis accelerometer. So you can change the settings and run on a given road at different settings to see the change in the impulse response of the car to road

Cat and Plasma Balls at https://www.youtube.com/watch?v=XkJYY4dDdr0 The cat investigated all parts of the globe, power (it can smell the hands of the person on the plug most likely), and behavior (optical, response to touch and nearness, acoustic because its ears and nose can pick up more than our fat fingers) methodically. Its nose is rather

Comment on The Civic Went on an Diet

The Civic Went A Diet with a serious weight reduction https://www.youtube.com/watch?v=TiZm7Ucm3JQ I think you can take off the back doors and replace them with lightweight panels. This made me think, I wonder what would happen if you could buy a “barebones car”, like “barebones computer”? No interior, no heater or AC, then add components as

Comment on making rubies in a microwave oven

How To Make Ruby in a Microwave at https://www.youtube.com/watch?v=ybcdRQmQcHQ It looks like the aluminum wire is burning (oxidizing) to aluminum oxide, and melting some of the close mixture. If you use coarse grained aluminum powder, and mix with the oxides, it might work longer and more uniformly. The melting point of aluminum oxide is 2072
