Well, it just isn't possible to get both effects at the same time, 
because you can only analyze one frequency at a time. The magnet 
produces a DC field, and the coil an AC field.

Anyhow, if you are interested in superimposing the fields manually, it 
is possible to dump data to disk, for example, off of a regularly 
spaced grid. You have to use Lua scripting to do it, but it's not 
that big a deal to do. There is an example at:

that might be helpful.
