Is it true that magnets forced into opposition lose magnetic their force?

AI Thread Summary
Clamping two permanent magnets together with like poles (N to N or S to S) does not cause them to lose their magnetic power. Evidence from electric motors shows that permanent magnets maintain their magnetism despite being subjected to opposing forces. Additionally, even in diamagnetism, a permanent magnet's attraction to like magnets remains unaffected over time, provided the Curie temperature is not reached. When two magnets are placed in attraction mode, it is akin to splitting a single magnet in half, which does not diminish their individual magnetic properties. Overall, the consensus is that permanent magnets retain their magnetism regardless of how they are positioned relative to each other.

Good morning wise friends!

Its a cold morning here in southern New Jersey, my Labrador Retreiver (Mocha) is at my feet and we're expecting snow tomorrow. (I love snow, makes me appreciate the spring!)

O.K., the question.

I have heard that two permanent magnets clamped together N to N or S to S will lose their magnetic power. Is this true, and can anyone explain why?

If true, does the same effect occur when the magnets are placed in attraction mode?

May you all have good health and happiness always...

Clamping two magnets together won't degrade their magnetizm. Evidence: the magnetizm of the permanent magnets in electric motors never lose their magnetizm, even though they are subject to constant and repeated magnetic opposition forces (torque). Also, in diamagnetism, the magnet in situ is exposed to a continuous repulsion, yet a permanent magnet's ability to attract like-magnets is never diminished with respect to time (assume Curie temperature is never reached).

Two magnets placed in "attraction mode" is the same thing as taking a single magnet and breaking it in half.
 

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'

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...
