Does the strength of an electromagnet depend on the number of volts passing through the wire or the number of coils of wire wrapped around the iron core?

The strength of an electromagnet depends on:
-- The magnitude of the current through the wire. (This depends on the voltage between the ends of the wire.)
-- The number of turns of wire in the coil wrapped around the iron core.

An electromagnet would have the greatest strength if its wire were wrapped around a core made of what?
iron
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.
What is the effect of increasing the number of coils of wire wrapped around the core of an electromagnet?
This causes the power of the electromagnet to be increased.

This causes the power of the electromagnet to be increased.
What is produced when a coil of wire is wrapped around an iron core?
electromagnet
An electromagnet would have the greatest strength if its wire were wrapped around a core made of what?
iron
What has a wire-wrapped core?
A coil of wire or a coil in the shape of a cylinder is a typical shape for an electromagnet (or a solenoid). The strength of the magnetic field of an electromagnet can be increased significantly if the coil is wrapped around an iron core. This configuration may be called an inductor when used as an element of an electrical circuit.
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.
What is a eletromagnet produced by?
I believe that it's spelled electromagnet. An electromagnet is produced by electricity flowing through a wire wrapped around a needle 30 or more times.
How can the magnetic field strength of an electromagnet be reduced?
Either increasing the size of the current (in amps) or the number of turns of wire wrapped around the core will make a stronger magnet. A larger current will make a stronger magnet (up until too much makes the wire melt!). Increasing the voltage forces more current through the electromagnet.
A coil of wires wrapped around a core?
A coil of wires wrapped around a core is an 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.
What kind of magnet is electromagnet?
An electromagnet is a piece of iron(usually a cylinder or rectangle)wrapped around with copper wire that when electricity runs through it it works like a magnet. Also called artificial magnet.

How do you use electromagnet in a sentence?
Electromagnetism occurs when an electric current is sent through a coil of copper wire that is wrapped round an iron core.
