What are three important ingredients for making steel?

The three important ingredients for making steel are coal, iron core, and limestone. Because steel contains iron, it is very common for it to develop iron oxide, or rust.


What material should you use for an electromagnet?

You should use a ferromagnetic material, such as iron or steel, to make an electromagnet. These materials have strong magnetic properties that are necessary for creating a powerful electromagnet.


Is the core of an electromagnet a piece of steel put in the center of the coil?

no


What is a better conductor copper or iron?

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 is hysteresis loss in transformers?

Hysterisis losses are the losses which are taking place in the iron or steel core due to reversal of magnetisation of steel core.


Can a wooden core change an electromagnet?

Yes, a wooden core would not affect the magnetic properties of an electromagnet since wood is not a magnetic material. For maximum magnetic strength, it is recommended to use magnetic materials such as iron or steel as the core of an electromagnet.
