A coil of something conductive to produce the electromagnetic field is the bare minimum. Most electromagnets also have a ferrous metal (which is magnetized in turn) core or housing as well.

What suitable material would you use for the core of an electromagnet?
Iron - use a bunch of iron nails, wrapped many times with insulated copper wire, if making your own electromagnet.
What material should you use for an electromagnet?
Soft iron core
What factors of an electromagnet affect the strength of the magnetic field?
One of them is how many coils go around the electromagnet. also the amout of current flow< and the type of core material.
What is a solenoid with a ferromagnetic core called?
Its called an electromagnet
What are the 4 ways to make an electromagnet stronger?
Use: More turns of wire A higher current A larger core area A core material with high permeability (soft iron instead of air for example)
Why is steel not a suitable material for core of an electromagnet?
steel is note for an elecromagnet because once it turned magnetic it stays magnetic

What material should you use for an electromagnet?
Soft iron core
What do the parts of an electromagnet do?
An electromagnet requires only two parts, a core of ferro-magnetic material and wires winding around it. The wires magnetize the core when current flows through them, and the core then creates the magnetic field which the electromagnet is intended to produce.
You can increase the strength of an electromagnet field by?
using a stronger ferromagnetic material for the core. :)
What is elelctromagnets?
Electromagnet is a device consisting of a core of magnetic material such as iron, surrounded by a coil through which an electric current is passed to magnetize the core.
How does the strength of an electromagnet with an iron core compare to an electromagnet that simply has air at its core?
Permeability of the medium, that too, if it is ferro-magnetic material then it gets increased to a larger extent and so the magnetic induction too increases enormously.
What factors of an electromagnet affect the strength of the magnetic field?
One of them is how many coils go around the electromagnet. also the amout of current flow< and the type of core material.
Can you use an aluminum core for the magnet?
I cannot remember for sure, but in an electromagnet, an aluminum core would not have any permeability to add to the electromagnet's strength. An electromagnet is more efficient when a thicker core is used; it generates more power. The material you use should be prone to magnetism, as in attracted by permanent magnetic apparatuses or the such. So, an aluminum bar/core (cannot be magnetized), like you stated, wouldn't be the best choice for your magnet's core.
What is a solenoid with a ferromagnetic core called?
Its called an electromagnet
Can an electromagnet create a magnetic field when the battery is removed?
If the electromagnet has a core, which has become magnetized, then the core will have a residual magnetic field when the power is removed.
What is the central part of an electromagnet?
A ferrous core.
