hey i am doind a piece of homework on electromagnets and i have to reaserch 3 examples and i have already done scrap yard can i have some help?

A scrapyard crane is a good example. You could also check out electric motors - they all have electromagnets in. You could also look at an MRI scanner- that has very powerful electromagnets in it.
