Invar can be used as magnetic core material, but there are

better choices. Invar is alloyed for its thermal stability. It is

iron with a good percentage of nickel. Remember that magnetic core

material is usually laminated or is "powdered" in a way to

electrically isolate the "bits" of core material so eddy currents

will be reduced. A link is posted to the article on Invar put up by

our friends at Wikipedia, where knowledge is free.
