Wire: The best wire for electromagnets is called magnet wire. It is simply copper wire with a very thin enamel insulation. It is thin so you can get as many windings possible on to your electromagnet. I am assuming you are going for a strong magnet. More windings = more power.
Core:
I would say the best cores are Soft Iron in terms of cost effectiveness and availability.
btw, all bolts and nails are made of steel which is not the same as soft iron.
There is a better option. You can buy something called a Ferrite Rod which will perform better, but a little more expensive and harder to come by. You can order it online. This is my recommend choice. However, it is brittle and must be handled with care. It is a ceramic and will break.
Last item on the list of cores is Mu-metal. Some people say this is the best material for a core. Don't bother with it. It is hard to come by, expensive, and not really worth it.
Tips: If you can try to get a core which is in a horseshoe/ C-shape. It will improve your performance.

∙ 13y agoThis is an important application, for at heart all electric motors and generators are electromagnetic in nature. The usual iron core materials are ferrosilicon alloys, with 15% to 90% silicon.
Usually made in the form of sheets of material, about 1mm thick. This design helps minimise eddy currents in the iron, which would cause hysteresis loss and therefore heat to be generated.

Donna is attempting to make an electromagnet to pick up old nails in and around her driveway Which of these materials would be best to use for the core in order to make the strongest electromagnet to?
u need 2 provide more information"Which of these materials would be best to use for the core in order to make the strongest electromagnet to?"u need to provide what "these materials" are
What material should you use for an electromagnet?
Soft iron core
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 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. :)
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.
Where is the electromagnet the strongest?
The strongest type of electromagnets are superconducting electromagnets. Usually these superconducting electromagnets are immersed in liquid nitrogen or liquid helium to cool them to near absolute zero. === === For non-superconducting electromagnets, the strongest electromagnets would have the greatest ampere turns over a large area. The core of the magnet would be a highly ferromagnetic material, such as iron, or a mixture of a ferrite and a ceramic. Very strong electromagnets used for lifting machinery have both poles on the bottom side which will maximize the magnetic field produced. Non-superconducting electromagnets will saturate and stop producing magnetic fields at about 2 teslas or so. This is the limit of magnetic strength of ordinary electromagnets.
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.
Which metals would make the best electromagnet core?
iron
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.
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
