If you buy framed whiteboards, ready-made for classroom use, they will be much more expensive.  For large, wall-mounted whiteboards, you can build a frame yourself.  Don't forget a "chalk" tray!  But, if you are going to use the wall-mounted boards for many classes over many years, it is probably worth investing in professional enamel-on-steel boards available from classroom suppliers.

We use a small model (about 10-15 cm) of a person to help students learn how to do proofs by contradiction when using Gauss' and Ampere's Laws.  While you can purchase dolls in this size, paper or cardboard cutouts work just as well and allow the students to decorate them (which a large percentage do).

The butterfly net is another prop which can be used when discussing flux, particularly magnetic flux. Specifically, the butterfly net exemplifies how different surfaces might have the same closed boundary.

==== Coordinate Axes ==== ==== Coordinate Axes ====
 +
 +Students encounter a variety of orthogonal coordinate systems in their courses on electrodynamics. To illustrate orthogonal coordinates, the instructor can use a set of coordinate axes with which they may place different labeled unit vectors, allowing students to visualize the coordinate system they are working with.

 +==== Paddle Wheel ====
 +
 +A paddle wheel (in this case, made out of snap-together constructive toys) can be used to demonstrate the effect of a force vector field on a physical system.

 +==== Pumpkin Quarters ====
 +
 +A pumpkin that has been sectioned into quarters can be used as an interactive physical representation of a spherical coordinate system.

 +==== Surfaces ====
 +
 +We use plastic surfaces of multivariable functions that are dry-erasable, transparent, and lightweight. The surfaces were created as part of the [[https://raisingcalculus.winona.edu/|Raising Calculus to the Surface]] and [[https://osuper.science.oregonstate.edu/content/raising-physics-surface|Raising Physics to the Surface]] projects. Surface Kits include a surface, its corresponding laminated contour map, and a slope measurement tool.

 +
 +
 +==== Contour Maps & Vector Maps ====
 +
 +We print out contour maps or vector maps and put them in dry-erasable sleeves. Often, our maps correspond to plastic surfaces.
