Question 6

An engineer is designing the core for an electromagnet to be used in a scrap metal yard. The electromagnet needs to easily magnetize and demagnetize so it can pick up and drop metal objects. She can choose between an iron rod and a steel rod.

Which rod should she use for the electromagnet core, and is this rod a hard or soft magnetic material?

A

Iron rod; hard magnetic material

B

Iron rod; soft magnetic material

C

Steel rod; hard magnetic material

D

Steel rod; soft magnetic material
