What is one advantage of using electromagnets instead of permanent magnets?
Electromagnets can be turned off and off
How do you use a sentence about electromagnets with an iron bar and copper coil?
The student tested his theory using electromagnets, an iron bar, and a piece of copper coil.
What are some of the uses of magnets and electromagnets in our daily life?
like using laptop
Why are electromagnets useful in motors?
Electromagnets are sometimes more useful because they can be turned on and off at will. This feature allows them to do things that other permanent magnets cannot do. High speed mag-lev trains use this ability to their advantage to propel themselves down the rails.
How are electromagnets different from magnets?

How does a TV take advantage of magnetic forces?
A television system takes advantage of magnetic forces by using electromagnets. These magnets control the electron beams, causing them to scan top to bottom and left to right.

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.
