Electromagnets do not stay charged. They work by maintaining and creating a field around an object. If the force is broken then the magnet will go weak as well.

How long will a material that becomes charged stay charged?
Materials will stay charged as long as the electrons have no way of entering or leaving the materials.
What is the flow of electromagnets called?
Electromagnets
What do electrons microscopes use to focus and magnify an image?
Electromagnets focus the electron beam on the specimen. This is a good advantage of electron microscopes over traditional light microscopes where lenses have to be used. Electromagnets can be used as electrons are charged particles and are deflected by magnetic fields.
Do electromagnets affect glue?
Electromagnets do not affect glue.
How are electromagnets different from magnets?
You can turn electromagnets on and off.
Do food processors have electromagnets?
Yes, food processors do have electromagnets.
Are all electromagnets magnetic?
All electromagnets are magnetic when they are turned on.
How are electromagnets different from permanent magnet?
You can turn electromagnets on and off.
Why your battery will not stay charged?
Don't charge it frquently.
How are magnets used in electromagnets?
An electromagnet makes a great door lock. The steel in the door will stay put until the electromagnet is turned off.
Why is it that charged objects wont stay charged for long?
Because there is no insulator attached to it to prevent escape of charge.
Where use electromagnets?
Inside of electric motors are electromagnets and permanent magnets. In a metal junk yard large electromagnets are used to pick up metal. In MRI's large electromagnets are used for imaging.
