I assume your core is a closed core -- if you try this with a straight
core
and no closed magnetic path your losses will be horrible.

	Open-cored power transformers were used and sold commercially back in
"the good old spark days", and construction plans can be found in the
old books.  However, all of these transformers had to obey the laws of
physics, and hence took a LOT more turns than a closed-core transformer.
