Electromagnets are used in vending machines to deciever real coins from fake ones. Electromagnets will sort counterfeit money from real money, because most counterfeit money is an iron alloy. Iron is magnetic and gets pulled by the electromagnet, while real coins are not effected.

Three uses of a permanent magnet are: 1. In the needles of compasses which are used to navigate airplanes and ships; 2. In fridge door seals, to hold the doors closed; 3. In loudspeakers and microphones, which need to have permanent magnets as well as electromagnets to work.
Does a washing machine make use of an electromagnet?
I'm pretty sure. Unlike a standard magnet, which possesses a constant magnetic field, electromagnets only posses a magnet field when electrical currents pass through them. Therefore when the washing machine is on it uses electromagnets.
How do cat scans use electromagnets?

If something is copied on a copier does the machine keep record of the copy?
No. A copier does not keep a copy of material that is copied. When a copier makes a copy of your material, the light shines on thousands of little electromagnets. It then uses those thousands of little electromagnets to hold the ink. After it has applied that ink to the page, it turns off those magnets and your copy disappears from the machine.
