Answer:
Electromagnets are can be used for industrial applications, such as magnetic elevators that use magnetic attraction to lift heavy objects or magnetic separators that are responsible for classifying ferromagnetic metals from scrap. They are also used in the application of Maglev type trains which is a system of train transportation that uses two sets of magnets: one set to repel and push the train up off the track, and another set to move the elevated train ahead, taking advantage of the lack of friction.
