The magnetic field in an electromagnet is actually produced by the coil of wires with a current running through it. However certain materials, termed 'ferromagnetic' materials concentrate the magnetic flux when a rod of the material is placed within the coil (termed the 'magnetic core'). The most common of materials used for this have been iron based.

Iron better than steel in electro magnets?
Yes, they are.
What is an example of a situation where it would be best to use certain types of magnets to attract different types of objects?
Electro magnets can be used to attract metals temperarily while permanent magnet would be used for compasses.
How are electro magnets different from other magnets?
An electromagnet can be turned on and off, with an electric current and a magnet can not turn off
Does the thickness or length of the nail affect the electro magnets strength?
yes
Why are magnets used?
Electro magnets can be very useful to carry heavy loads of iron and metal from one side of a factory to another. Electro-magnets are formed by shooting electricity through a coil of copper.
What are electro magnets used for?
They can be used in Junk yards to pick up junk. They can be used in a Dentist.
What are electro magnets used in?
car wreck (scrapyards) metel dedectors at airports
Which magnets can retain their property for a short period of time?
Electro-magnets
Do magnets repel non magnetic materials not including electro-magnets?
of course not.

What form of magnetism must be used when constructing a magnetic crane?
Electro Magnets are the controllable type of magnet used. It may be possible but not practical to use rare earth magnets.
What is the Industrial Magnets?
Industrial strength magnets are used widely for lifting, work holders,and chucks.
Are bar magnets stronger than electro magnets?
Yes, because electromagnets can lose their magnetism.
Are electro magnets sometimes called artificial magnets?
Yes, electromagnets itself is an artificial magnet.
How are electromagnets used to make electric power?
Electromagnets are used to make electric power because magnets are a type of electricity,and electro is at the front.
Iron better than steel in electro magnets?
Yes, they are.
