    Electric Gas
AI Thread Summary
The discussion focuses on finding a gas that is resistant to electrical arcing and plasma formation, with an emphasis on ease of handling and lightweight properties. Sulfur hexafluoride (SF6) is mentioned as a candidate due to its use in waveguides, although it is heavier than air and classified as a greenhouse gas. Alternatives like argon, helium, carbon dioxide, and nitric oxide are suggested for their use in electric arc welding as shielding gases. The need for a gas that balances these characteristics remains a key concern. Overall, the search continues for an ideal gas that meets the specified criteria.

Im looking for a gas which is resistant to electrical arcing and turning into plasma, preferably being easy to obtain and handle, as well as being as light as possible. (Like helium). Thanks!

EDIT: More research suggests sulfur hexaflouride or (maybe) nitrogen. http://en.wikipedia.org/wiki/Dielectric_gas

Sulfur hexafluoride (SF6) is a gas used in waveguides to reduce arcing. However, I'm not sure if it is "easy" to handle. It is a greenhouse gas. And it is heavier than air, so it isn't "light".

Argon, helium, carbon dioxide, nitric oxide and others are used in electric arc welding as a shielding gas. Some of those gases may suit your purpose.
 

Thread 'Maxwell stress tensor'

This is from Griffiths' Electrodynamics, 3rd edition, page 352. I am trying to calculate the divergence of the Maxwell stress tensor. The tensor is given as ##T_{ij} =\epsilon_0 (E_iE_j-\frac 1 2 \delta_{ij} E^2)+\frac 1 {\mu_0}(B_iB_j-\frac 1 2 \delta_{ij} B^2)##. To make things easier, I just want to focus on the part with the electrical field, i.e. I want to find the divergence of ##E_{ij}=E_iE_j-\frac 1 2 \delta_{ij}E^2##. In matrix form, this tensor should look like this...

Thread 'Applying the Gauss (1835) formula for force between 2 parallel DC currents'

Please can anyone either:- (1) point me to a derivation of the perpendicular force (Fy) between two very long parallel wires carrying steady currents utilising the formula of Gauss for the force F along the line r between 2 charges? Or alternatively (2) point out where I have gone wrong in my method? I am having problems with calculating the direction and magnitude of the force as expected from modern (Biot-Savart-Maxwell-Lorentz) formula. Here is my method and results so far:- This...
