Question

What type of magnet is fitted on a crane to separate scrap iron objects from a heap of waste materials in factories?

Answer 1

Electromagnets are fitted in cranes to separate scrap iron objects from a heap of waste material in factories.

Waste materials supplied to factories contain a number of scrap metals including iron ore. So, in factories, scrap iron is separated from the heap of waste materials by using big electromagnets fitted to a crane.
