[NewCandle] Aluminum and Copper Disc Weight Effects

[Frederick Sparber]

Hi Nick and All.

A Googled up Quality Float Works:

*http://www.metalfloat.com/product/monelaluminum.html*<http://www.metalfloat.com/product/monelaluminum.html>

and placed an order for a 2.5 inch dia. x 3.625 inch copper "float"
(105.5 grams) and a 3.5 inch diameter aluminum sphere "float" (82.4 grams)
with 1/4-20 female thread receptacles, along with two 12 1nch
brass rods with 1/4-20 threads.

I want to see if Keith's dipole action wrt the fair weather field will pull
it around a pivot point.
