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.
The number of gallons of water that a washing machine uses varies between models. The standard washing machine uses 40 gallons of water.
Electromagnet which uses electric current can be turned on and off.
The average washing machine is said to use 65 liters of water per cycle. It is more energy efficient to fully load the washing machine because a half wash uses the same amount of water as a full wash.
Research
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.
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.
CAT Scan does not use electromagnets, its MRI (Magnetic Resonance Imaging) which uses Electromagnets to produce images of the patient's body.
Anything that uses electromagnets to work, such as credit cards, monitors, or hard drives.
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.
Electromagnets
NO,THEY ARE NOT......only uses a normal magnet at the door.

Electromagnets
Electromagnets have several uses. They are used in cranes to pick heavy metal objects, to lift tiny metal scraps from wound by doctors, motor and generators, electric bells, loudspeakers, etc.
Electromagnets are primarily used to produce electricity Any large scale facility with lots of instruments will definitely have electromagnets in it. Generators in the powerhouse uses big electromagnets to produce AC voltage which is then transported for the commercial or residential use.
It uses electromagnets.
