Creating a Magnet at Room Temperature

AI Thread Summary
Not every substance can be converted into a magnet at room temperature due to the nature of electron pairing, which cancels out magnetic properties. While all fundamental particles have magnetic characteristics, only certain materials exhibit coordinated magnetic behavior. The discussion suggests that isolating a molecule with an odd number of electrons could theoretically allow for magnetization. However, practical methods for achieving this across all substances remain unclear. The feasibility of creating magnets from all materials at room temperature is largely limited by their intrinsic properties.

How can every substance be converted into a magnet (at room temperature)?

No, not every substance can be converted into a magnet. Why do you say that ? May I know please ?

Are you asking a method to convert every substance to magnet ,or are you asking how it can be converted to magnet ?

Not sure the context of your question, but fundamentally every electron, proton and neutron is a tiny magnet. Most substances do not show coordinated magnetic behavior of the electrons (the strongest magnets) at room temperature.

... but I suppose, if you got down to one molecule of a substance and made sure it had an odd number of electrons (the electron magnets tend to pair and cancel themselves out), you could in theory convert the substance into a magnet.
 

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...
