It's A Fun Project Which Latter Has A Practical Application

In this project you'll discover how to change the windings on a transformer to get different voltages and currents.

For this metal melter just a couple of turns of heavy wire around the transformer core reduced the voltage to a couple of volts but upped the current to a whopping 800 A.

With the resistance of iron, that's more than enough to melt it

If you are going to attempt this project you may want to consult an electrician to get the safety tips you will need to stay alive.
