Milk pan for induction hob
It doesn't matter. Any pan that works on an induction hob will work for heating milk on it. And especially with the speed of induction, you will not notice much difference with different pans. 

By the way, there is no reason to want an especially conductive pan for heating milk. Milk burns easily on the bottom when heated too quickly, so being more heat conductive is more likely to be a liability. I have personally not seen copper pans being suggested especially for milk, the traditional milk-specific pans I've seen are either thin enamelled steel or special stainless water-bath gizmos with a whistle.
