Force between two electromagnets due to direct flux and radial flux

AI Thread Summary
The discussion focuses on calculating the force between two electromagnets with a rectangular cross-section, specifically in face-to-face and radial configurations. Key factors influencing the force include whether the magnets contain iron and their proximity to each other. For precise calculations, especially in dynamic scenarios where one magnet rotates, reliance on finite element method (FEM) software is recommended. The initial force can be determined with specific details about the magnets, such as induction levels. Overall, additional information is necessary to provide accurate formulas or calculations.

I want to know about the FORCE BETWEEN TWO ELECTROMAGNET OF RECTANGULAR CROSS-SECTION. The force due to the fluxes both direct face to face and radial seperately. Also I like to get the exact formula or the source from where I get that. Can anyone help me? pls.
 
Physics news on Phys.org
Nobody know about this?
 
Well, if you can simplify the situation, then there are answers. For instance:

- If your magnets have no iron

- If your magnets have iron and are close enough, and preferably you know the induction

So if you give more details, maybe you get an answer. In the general case, there is none. You'd have to rely on an FEM software.
 
At first ,Thanks for ur reply
ie situation is two electromagnets. One is fixed other is moving. At first they are in face to face. Then the moving magnet start rotating in its on axis. I want to find out the force at initial position and force when it moving also.
If u have any idea pls reply.
 

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...
