Magnetic Shielding: Preventing Interference of Magnets

AI Thread Summary
To prevent interference between two magnets, a substance known as "mu-metal" is suggested for magnetic shielding. A sheet of paper is ineffective in blocking magnetic fields, highlighting the need for specialized materials. The effectiveness of any shielding material is contingent upon the strength of the magnetic field being addressed. It's important to note that no material can completely shield against an arbitrarily strong magnetic field. The discussion emphasizes the need for appropriate materials to achieve effective magnetic shielding.

Is there a substance that can be placed between two magnets that will stop one from affecting the other? If a sheet of paper is placed between the magnets it has no affect. This is obvious but what i want is a substance that can be placed between two magnets that are placed very close together and one magnet will have no affect on the other.

You want a magnetic shielding. You may want to look into something called "mu-metal".

Note that the effectiveness of shielding depends on the magnitude of the field. Nothing can shield a magnetic field of arbitrary strength.

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...
