Summary

COI synopsis: Recycled scrap metal is increasingly being used as raw material for steel. Huge flat electromagnets move this scrap to furnaces for melting; but because of their shape their magnetic field captures only the top layer of scrap on the heap. Now their efficiency has been dramatically improved by a simple change in design - an electromagnet shaped like a cone, which dives deep into the scrap pile, moving twice the metal in the same time and for the same energy.
