Magnetic Field -- break in the continuity of a conductor

AI Thread Summary
A break in the continuity of a conductor affects its magnetic field and resistance, as a continuous circuit is essential for electric current flow, which generates a magnetic field. Resistance is influenced by the effective cross-sectional area of the conductor, and microscopic fractures can further complicate this. Detection methods for such fractures include reflectometry and measuring the conductor's resistance. Reflectometry can be effective even for low-frequency radiation, although the discussion primarily references x-ray reflectometry. Understanding these concepts is crucial for analyzing conductor performance in electrical applications.

Hi! Just curious...
Does a break in the continuity of a conductor's volume affect its magnetic field, resistance, etc?
 
Physics news on Phys.org
A continuous circuit is necessary for an electric current and an electric current of charges is required to generate a magnetic field. Now if you mean a nick in the volume, then resistance is proportional to the effective area of the conductor.
 
thanks for the reply.
what if the cross-sectional area of a conductor is not uniform, say there are microscopic fractures in a certain region, is there some way to detect this?
Does this make sense?
 
Sure, makes sense, and yes, many ways. Reflectometry from my experience, or merely resistance of the conductor.
 
this is just amazing! does reflectometry work even for low-frequency radiation? I only know xray reflectometry.
 

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...
