Here is our Team's reply:
Circular coils are just as effective as Polygon (or Triangle) Coils:
We can wind most any type of coil you wish as long as you give us the dimensions.
We should have a 12" - 16" Diameter Coil available shortly if that interests you?
If you like, we can add as many magnets as you wish.
We use Ceramic Magnets, circular or rectangular, that we obtain locally at Hardware Stores.
Are you looking to use one in a bath tub?
Tony from Herbs Plus and Beadworks makes those.

We have a few requests for the "Triangle" style coils but in our experience and measurements with our equipment, the shape is not an improvement over a circular Coil.
The magnetic field produced by a circular coil will be rotationally symmetric, which will not be the case with the triangular coil.
Here is some excellent reference material, the key point being the same as our measurements, i.e. Circular coils are just as effective as Polygon (or Triangle) Coils:
FORMULAS AND TABLES FOR THE CALCULATION OF THE INDUCTANCE OF COILS OF POLYGONAL FORM.
By Frederick W. Grover.
Quote from the first page of the book:
In this paper formulas are derived for the calculation of the inductance of such coils. The cases treated are triangular, square, hexagonal, and octagonal coils. It is found that a circular coil enclosing the same area as the polygonal coil, the length and the number of turns being the same in both cases, has nearly the same inductance as the polygonal coil.
We hope this answers your questions, if not just ask.
