• B. permanent magnets
• C. both A and B
• D. none of the above

Answer 1

Answer: (A)

electromagnets

An electromagnetic crane is a type of crane with an electromagnetic lift. Electromagnetic cranes are commonly utilized in lifting and moving various scrap metals. It does not have the mechanical 'pincers' of a regular crane, instead, it has a large flat magnet which draws the metallic materials to it.

Using the principle of electromagnetic induction, these large machines are used to handle scrap ferrous metals, such as iron and steel, which can be found in junk yards and recycling plants.
