How is scrap iron separated from the waste materials in factories?
Asked by Topperlearning User | 08 May, 2014, 07:05: AM
Expert Answer
In factories, scrap iron is separated from the heap of waste materials by using big electromagnets fitted to a crane. When a such a crane is lowered on to the heap of waste materials, then the scrap iron objects present in the heap, cling to the electromagnet. The crane is then moved up and away to drop these scrap iron objects at a separate place.
