    While I was scrapping an old radio for entertainment I found a ferrite 
rod about 1/2" wide and about 4 1/2" long. Since I have read about the 
advantages about having ferrite in the center of the secondary, I have 
decided to build a small coil around it. I have two questions:

1) Can I power it with very little power? (like strait out of the wall, or a 
6.5kv xformer powered by a car battery?) I am only planning on playing with 
it, I don't intend for it to be very impressive.

2) It is slightly oval, two of the sides are flattened will this affect it?
