How is scrap iron separated from a heap of waste materials in factories?


Scrap iron is separated from a heap of waste materials in factories by using large electromagnets fitted to a crane. 

  • The electromagnet fitted crane is moved up and away from the waste to drop these scrap iron objects at a separate place.
  • Electromagnets are used for this purpose because one can switch on and off the supply of magnetism during the process of lifting and dropping iron pieces.
