Expert Answer:

An electromagnet is fitted to the long arm of a crane. This long arm of crane is lowered over the heap of waste material. When the electromagnet is switched on, the iton junk from the garbage sticks to the electromagnet. Then, the arm is lifted up and moved to another place where the iron junk is dropped by switching off the electromagnet.
