Dear Mr. LPFR:
Thanks a lot for the answer.
Could you please post the source of the paper (which gave force ~ H * grad(H)) if you happen to find it again?

Dear lpfr,
Thank you very much for the reply!
I have a computer code to calculate the force due to drag (viscous force). For the first attempt to attack this problem, I will ignore the Brownian motion and electrical chage for now. And, I will consider one 1 particle so that there is not...
Hi,
I have a permanent magnet (actually, an assembly of permanent magnets). I can calculate magnetic flux density induced by the magnets (when no other objects presents).
Now, I have very small iron particles suspend in water inside a cup. The magnets are then placed on the outside wall...
