    All kinds of things!  Electromagnetic items are primarily used when you only want magnetism for a certain amount of time, like, say, when you want to pick up something with a magnet, then let it drop, like a car in a junkyard. 


    Also, electromagnets can be used for locks, since a person may want something to be locked most, but not all, of the time.

    They are also used in speakers and neon signs.  Check the first citation for more info!
