The nail in an electromagnet is the core of the electromagnet. It is there to provide the magnetic lines of force a "highway" to get from one end of the coil to the other end through the middle of the coil. The magnetic lines of force "like" the nail because it is a ferromagnetic material. They can travel through it very easily - and they do! The nail also provides the "working end" of the electromagnet. The magnetic field lines emerge from the nail, and then act on what is there. If you are, say, doing a separation experiment removing steel tacks that are mixed in with small brass nails (brads), the tacks will stick to the end of the nail at the "working surface" or the pole of the electromagnet.

What is a stronger electromagnet - a nail or a bolt?
Bolt
What effect does decreasing the number of coils around the nail have on the strength of the electromagnet?
Decreasing the number of coils reduces the strength of the magnet.
How does the strength of a wooden core electromagnet compare with that of the iron core electromagnet?
Electromagnets consist of wire coiled around a core. The core can be anything from air to a nail or even a pencil. Since electrons flow freely through a conductive core (like a nail), an electromagnet made with a metal core will have a larger magnetic field (and thus be stronger) than an electromagnet with a wooden core. The strength of an electromagnet is related to the number of times the wire is coiled around the core and the distance the wire covers across the core. The more coils wrapped closer together, the stronger an electromagnet will be. The amount of voltage running through the wire also plays a role in an electromagnet's strength. More voltage means more electrons moving through the wire and thus a stronger magnet.
Does an electromagnet work without a nail?
Yes but you would need a conducting pole of some kind to create the magnetic field.
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
Should the nail be straight in the electromagnet?
yes
What is a stronger electromagnet - a nail or a bolt?
Bolt

What is used to produce an electromagnet?
A Battery, wire, nail/metal cylinder.
How do you make a electromagnet stronger?
For a simple copper wire around iron nail electromagnet, increasing the number of rounds the copper wire makes around the nail will increase the electromagnet's strength. Also, increasing the voltage applied(adding a battery) will increase the magnetic field.
What is a nail wrapped around a wire and connected to a battery called?
it is called an electromagnet
A wire that carries electricity and is coiled around a nail makes a simple?
electromagnet
What will happen if a wire is wrapped around a nail a lot of times?
If the nail is iron and you pass an electric current through the wire then you have an electromagnet.
When you make a homemade electromagnet with wire and a nail and a battery does stripping the wire that is coiled around the nail make the electromagnet stronger?
No, this will stop the magnet from functioning and is the same as using a short thick wire instead of a long coiled wire.
A Study was done with an electromagnet system made from a battery and wire wrapped around a nail. Different sizes of nails were used the number of paper clips that the electromagnet could pick up?
i am pretty sure the size of nail doesn't matter.
What does an enameled wire that's wrapped around an iron nail connected to an electrical circuit create?
An electromagnet.
What materials do i need to make an electromagnet?
A nail, copper wire, paper clips, staples and power supply.
