Beginers Simulation Tool Needed
Beginers Simulation Tool Needed
(OP)
I would like to ask for recommendation regarding tool/software application for basic (but correct) simulation of magnetic fields and calculation of magnetic force for experiments with permanent magnets. I downloaded Vizimag 3.18, however this tool is very limited and does not meet my expectations. Please advice. Thank you.

The problem is a calculation of a magnetic force (I need just 2D simulation/calculation)
Does anyone know a correct formula to calculate force between two permanent magnets (same materials, same characteristics) that have different sizes (block magnets: x,y,z) when you know distance between them as well as angle..?
Thanks.

FEA is usually the preferred method in these instances. If you just need 2D simulation, there are some freeware programs available in that FAQ. Each program will have a learning curve associated with them, but it is usually worth the effort.

johnblack: Are you trying to calculate attractive or repulsion forces between your magnets?

Fairly to use interface directly in FEMM
Easy to interface with Matlab to automate tasks such as building geometry and analysing results.

I am not aware of any analytical solution for the general problem of attraction between two magnets. I guess you can solve a bunch of similar problems and try to build a correlation to a simple function for that class of problems (empiracal vs analytical solution). Of course 2d FE solution is also sometimes also a poor approximation of real world problem, depending on the geometry
