Query: Pan is Useless

I own an INDUCTION cook-top stove.This cook-top cooks using magnetic energy.The magnetic energy cooks by vibrating the metal in the cooking utinsil only, which must be made of a magnetic material, such as steel or iron.All-Clad is noted for being made of steel but I was not told that this pan has an aluminum outside shell, which is non-magnetic. Thus, I own a great pan that is useless to me!Not all All Clad cookware can be used with an Induction stove! Ask mfr. before buying.
