Continuum of Calculate pull force of magnet?

[shahid.arshad]

Hi Guys,
I am going to restart the discussion in the following thread
https://www.physicsforums.com/threads/calculate-pull-force-of-magnet.162157/

I working on similar system where i am interesting to calculate the pull force of permanent magnet on nanoparticles in water suspension. I am not familiar with programing languages, I am wondering if you guys know/have some tool/program/code to calculate pull force on nanoparticles. I will be very grateful for your help

with kind regards
Shahid

Hello Shahid,

Thank you for restarting this discussion and bringing up an interesting topic. The pull force of a magnet on nanoparticles in a water suspension can be calculated using several methods. One approach is to use the magnetic dipole-dipole interaction equation, which takes into account the magnetic moment of the magnet and the magnetic susceptibility of the nanoparticles. This equation can be solved using a program such as MATLAB or Python, which have built-in functions for calculating magnetic interactions.

Another approach is to use the Langevin equation, which takes into account the thermal energy and Brownian motion of the nanoparticles in the water suspension. This equation can also be solved using a programming language or a specialized software such as COMSOL Multiphysics.

I recommend researching and familiarizing yourself with these equations and their applications in order to accurately calculate the pull force of the magnet on your nanoparticles. Additionally, there may be online calculators or software specifically designed for calculating magnetic interactions in suspensions that could be helpful in your research.

I hope this information helps and good luck with your project!
