Question: What is the lowest relative permeability with skin depth greater than 0.112 inch in induction cooking?

Question: What is the average relative permeability when the resistivity is less than 1.12 and the surface resistance to copper is less than 1 in induction cooking?

Question: What is the sum of the skin depths with a resistivity of 1.12 and a relative permeability greater than 1 in induction cooking?
