An induction furnace is an electrical furnace in which the heat is applied by induction heating of metal. [ 1 ] [ 2 ] [ 3 ] Induction furnace capacities range from less than one kilogram to one hundred tons, and are used to melt iron and steel , copper , aluminum , and precious metals .
Induction heating is the process of heating electrically conductive materials, namely metals or semi-conductors, by electromagnetic induction, through heat transfer passing through an inductor that creates an electromagnetic field within the coil to heat up and possibly melt steel, copper, brass, graphite, gold, silver, aluminum, or carbide.
Heating the cookware (such as in a hot oven or on a stovetop) facilitates the oxidation of the iron; the fats and/or oils protect the metal from contact with the air during the reaction, which would otherwise cause rust to form. Some cast iron users advocate heating the cookware slightly before applying the fat or oil to ensure it is completely ...

Induction-compatible cookware can nearly always be used on other stoves. Some cookware or packaging is marked with symbols to indicate compatibility with induction, gas, or electric heat. Induction cooking surfaces work well with any pans with a high ferrous metal content at the base. Cast iron pans and any black metal or iron pans are compatible.
The resistance of a cast iron pot is lower than that of a copper wire coil, not higher. The reason for selective heating is not the resistance difference, it is the 2 facts that: eddy currents in the iron can and do short out. If the iron were made in a similar wound insulated strip fashion to the copper coil, it would not heat due to eddy ...
