Given the context of your question i can only assume you are referring to the CORE of an electromagnet. In that case, the more dense the magnetic material you are using the better. In the case of Copper,while dense, it's very weakly magnetic and does not make an effective core. Steel is an alloy and while harder than Iron, is not as dense. Iron, being a denser magnetic material, makes a very effective core for an electromagnet to wrap your insulated copper wires around. I would suggest using Iron; however steel should also work for the purposes of demonstrating the concept of an electromagnet.
What else can I help you with?
Why iron is not a good conductor of heat if it compair to copper?
Copper has relatively easily available electron as compare to the iron because copper has bigger atomic size than iron which means the shielding effect in copper is more than iron so the electron of copper can conduct heat more easily and efficiently as compare to the electron of the iron which make iron not a good conductor of heat if it is compair to copper.
Is nickel a better conductor than copper?
No - copper is a better conductor than nickel.
Is ice a better conductor than copper?
No, Ice is a good insulator and copper is a very good conductor
Why are copper wires used instead of steel wires?
I think copper is cheaper.
Which is a better conductor of electricity copper or silicon?
Silicon is only a semiconductor. Copper on the other hand is used to make wires and is an excellent conductor of electricity.
What makes a better conductor copper or iron?
Copper is better conductor than iron because copper has higher electron affinity of 1.22948 eV than iron which is 0.16299 eV.
Why is most wires made from copper not iron?
Copper is a much better electrical conductor than iron.
Which is the least conductor among iron copper aluminum?
Between iron, copper, and aluminum, copper is the best, followed by aluminum, and last by iron. Gold is often plated over other metals because it is even better and resists corrosion.
Why iron is not a good conductor of heat if it compair to copper?

What it meant by good conductor?
.Something that carries something better than average. For example, copper is a good conductor of electricity. Iron is a good conductor of heat.
Is copper or aluminum a better conductor?
copper is better
Why is copper a better condutor of heat than iron?
Copper is a better conductor of heat than iron because it has a higher thermal conductivity. This is because copper's atomic structure allows heat to transfer more efficiently through its lattice. In contrast, iron has a lower thermal conductivity due to its crystal structure which hinders the flow of heat.
How do the physical properties of iron and copper compare?
Iron is a harder and more brittle metal than copper. Copper is a better conductor of electricity and heat compared to iron. Additionally, copper has a reddish-orange color while iron is a silver-gray color.
What are example of conductor of electricity?
iron, copper, silver
What has the lowest resistance copper wire or iron wire?
Copper wire. .wikipedia.org/wiki/Electrical_resistivity_and_conductivity
Which is a better conductor of heat air or a copper wire?
A copper wire is a much better conductor of heat than air is.
What metal is the best conductor of heat aluminium iron or brass?
Aluminum have better thermal conductivity than ironAluminum: 205W/(m K)Iron: 80 W/(m K)
