What are some uses of electromagnets?
In general, electromagnets are used to move things; whether it be ultra small things like molecules or super large things like locomotives or cruise ships. MRI systems use electromagnets to "move" or at least change the polarity of molecules then measures the amount of electromagnetic energy created when the molecules move back. (yes, that's an oversimplification) Tape recorders use electromagnets to move iron oxide molecules on a tape, forcing a specific magnetic orientation of the molecules that can be read when the tape passes a tape read head. Electromagnets are used to move armatures of electric motors, and the armatures are connected to shafts that rotate, propelling a cruise ship or a locomotive. Electromagnets "move" the electron beam of a CRT, allowing the picture to be displayed on older televisions. That is just an example of a few uses of electromagnets. Keep looking, they are all around us.
What is a device that uses electricity and is used to make things move?
Electromagnets
How are electromagnets different from magnets?
You can turn electromagnets on and off.
How are electromagnets different from permanent magnet?
You can turn electromagnets on and off.
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.
Does the coil of wires move with the electromagnets while producing electricity?
no

Electromagnets
Why cant large materials move across the membrane by facilitated diffusion or active transport?
because of lipid insolubility
Materials that are not digestied move into...?
Materials that are not ingested move into the colon or large intestine.
What is the flow of electromagnets called?
Electromagnets
Do electromagnets affect glue?
Electromagnets do not affect glue.
How are electromagnets different from magnets?
You can turn electromagnets on and off.
Does digestion move materials into the cell?
Digestion breaks down materials into easily absorbed components. Absorption and diffusion move materials into the cell.
How do scrap yards separate metals from non magnetic metals?
They use electromagnets to separate magnetic metals from non-magnetic metals/materials in scrapyards.
How can you move a mountain?
We cant move mountains. Mountains move themselves
