Most often, a soft-iron core, which becomes the actual magnet
when the current is flowing in the turns of wire around it.
------------------------------------
An iron core. The simplest electromagnet can be made by wrapping an iron nail (common construction nail) with a copper wire (insulated not bare copper) and attaching both ends of the wire to a battery. The more wraps and the higher the voltage the stronger the magnetic field produced.
Note: an electromagnet can only be made with DC electricity, as AC electricity will constantly reverse polarity 50-60 times per second!

How is a magnetic force in an electromagnet created?
An electromagnet uses electricity to create the magnetic field. Moving charges create magnetic fields. Knowing that, if we have a lot of copper wire (with a suitable insulator) wrapped around an iron core, we can send direct current through that wire, and it will create a magnetic field. The magnetic field will magnetize the iron core, and the core becomes a magnet. Wrapping wire around a nail and connecting a battery to the ends of the wire will make a simple electromagnet.
Two ways to increase the strength of an electromagnet?
Increasing the number of coils in the wire winding around the core and increasing the current flowing through the wire are two ways to increase the strength of an electromagnet. Both of these factors contribute to creating a stronger magnetic field in the core, increasing the electromagnet's overall strength.
List the factors on which the strength of the magnetic field of an electromagnet depends?
The strength of an electromagnets magnetic field depends on:The type of core metalThe ability of the wire to carry current (its material and thickness)The number of turns of the wiring around the coreThe voltage/current of the electricity going through the wire.
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.
How does electricity produce magnetism in an electromagnet?
An electromagnet uses an electric current flowing through a wire. That current creates a magnetic field around the wire and is the basis for Ampereâ??s circuital law. In electromagnet can be amplified by both increasing the charge, and also wrapping the wire around a soft metal like iron.By electricy i think
Metal core wire and what are needed to make an electromagnet?
To make an electromagnet, you would need a metal core wire (such as iron or steel) and a power source, such as a battery or electrical current. The metal core wire is wrapped around a core material and the electricity passing through the wire creates a magnetic field around the core, resulting in the electromagnet.
How did Bell use the electromagnet in the telephone?
He wound wire around it to make a tranformer.
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.
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?
Stripping the wire in a homemade electromagnet would not make it stronger. The number of coils and the current passing through the wire are the main factors that determine the strength of the magnetic field produced by the electromagnet. Stripping the wire would affect the conductivity and integrity of the coil, potentially reducing its effectiveness.
How do you make an electromagnet with a rivet and a wire?
Wrap the wire around the rivet as many times as you can, and connect the ends of the wire to a battery.Turning on the electricity turns on the electromagnet. More turns of wire means a stronger magnet.See also related Wikipedia link.
What must flow through the coil of wire to make the electromagnet work?
An electric current must flow through the coil of wire to make the electromagnet work. This current creates a magnetic field around the coil, inducing magnetism.
What are the three things we need to make an electromagnet?
To make an electromagnet, you need a magnetic core (such as iron), an insulated wire to create a coil around the core, and a source of electric current to flow through the wire and create a magnetic field.
How do you make an electromagnet field stronger?
To make an electromagnet field stronger, you can increase the number of coils in the wire wrapping around the core, increase the current flowing through the wire, or use a core material with higher magnetic permeability. These methods will help increase the magnetic field strength of the electromagnet.
Does using thicker wire make a electromagnet more powerful?
The wire in a electromagnet is the conductive property transferring power. The thicker the wire the more power transferred to the electromagnet for a exponential amount of power.
What was wrapped around an iron bar to create the first electromagnet?
A copper wire was wrapped around an iron bar to create the first electromagnet.
What do you need to make and electromagnet?
To make an electromagnet, you will need a core material (such as iron or steel), insulated copper wire, a power source (such as a battery or power supply), and a way to connect the wire to the power source (such as a switch). Simply wrap the wire around the core material, connect the ends of the wire to the power source, and when current flows through the wire, it will create a magnetic field in the core, turning it into an electromagnet.
How you can make a magnet?
An electromagnet can be made by wrapping a copper wire many times around an iron bar and applying a direct current to the wire.
