Question

Name the method used to pick up iron objects from garbage

Answer 1

Answer:

Waste materials supplied to factories contain a number of scrap metals including iron ore. so, in factories, scarp iron is separated from the heap of waste materials by using big electromagnets fitted to a crane. When a crane fitted with a powerful electromagnet 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. In this way, scrap iron is separated from the heap of waste materials.
