| Hello, I have some questions.
Does somebody have the magneticpendulum problem solved as a mathematica
notebook, which he can send me?
If not can somebody explain my how i can solve that problem? I have to simulate a magnetic pendulum in mathematica.
thx a lot

| Martin,
Just start a Mathematica Notebook. Use Sections to organize your work.
Perhaps you will make a Statement of Problem section where you will define
your equations, parameters and initial conditions.
Then make a Solution Section where you will try to solve the equations using
NDSolve. Once you get your solutions you can try to plot them.
Maybe you will have additional Sections treating specific cases or classes
of cases. Maybe you will want to check simplified cases where the solution
reduces to an ordinary small oscillation pendulum.
You will probably have to use trial and error to get to a useful point. If
you have real trouble at some point, say with the differential equations and
how to feed them into NDSolve, post the equations and your attempt to this
group. There are many people here, not me, who know a lot about differential
equations and will probably give you good help. Post the code by converting
the cell to InputForm and then copying and pasting into a posting.

Well,
Do you really think that Mathgroup is a mailing list for copying homework
assignment ???

| Nice way of saying "don't ask us to do your homework for you," David. :-)
Martin, show us your attempt at trying to do it and where you're having problems
and then the newsgroup can help.

Try typing "magnetic pendulum mathematica" (without the quotes) into
Google and see what happens...

| You should note that the first site, which actually shows a calculation,
is not actually doing a magnetic pendulum. The force law quoted is that
for an electrostatic pendulum. The magnetic force in the problem is a
dipole-dipole interaction, and that is not used on the website.
