Someone hurry and make this.......
I got this idea abot 5 years ago when first starting to make Tesla coils. Take about 100 small (very small) coils and arrange them in a horizontal grid laying flat, then arrange 100 more next to them standing on edge, and you will have a 3d magnetic camera for visualizing a magnetic field. Some of these new chip inductors may work well for this. If someone wants to patent this, at least give me some credit.

Re: Magnetic camera --> Improved! GMR
Instead of using coils or inductors, use GMR (Giant Magneto Resistance). You can make them real tiny and they will provide a signal 10 to 100 stronger than a coil would, and have a much quicker response. You can make crude devices by stacking alternating sheets of ferris and non-ferris metals. Resistance will change depending on the strength of the field.
Although, I doubt you would see anything interesting with such a camera.

Re: Magnetic camera
Why not use Magneto-Optic Crystals...or Faraday Glass elements? These rotate the plane of polarization of light in proportion to the scalar (or "dot") product of the magnetic field and light path. You would need one plane of elements for each axis of field you would like to "image" , just as you would for the sets of coils, for a full 3D imaging capability.
The basic problem with 3d imaging or either magnetic or electric fields, is that one needs to do a tomographic process to make the 2D data sets into a 3D shape. The process is much like the CAT Scan methods of turning 2D Xray sillouettes into a 3D -like image of your innards.
To define the interior of a solid you need to construct N^3 volume elements from sets of N^2 area elements. Thus the many angles of orientation to provide the required additional N elements.
An interesting problem.
Much more difficult yet, is determining what's actually going on inside the Fusor during either the demo or the real fusor mode.
Handling the gas dynamic and space charge and... etc etc... is the task of super computers, which do not apparently succeed well enough at the models to correctly suggest what should be done for the fusion efforts to be successful in the Bazillion -Buck efforts.
