I know you can used iron wrapped around with copper coil to create electromagnet , can it be done with steel? Or must it always be iron?
You can certainly create an electromagnet with a stainless steel core. You can create an electromagnet with a paper core. It is just that the strength of the magnetic field will not be as high as with a soft iron core. The reason is that the iron molecules in pure iron are like little bar magnets that can align with a magnetic field and thereby increase the magnetic field strength. Paper molecules are not like that. Stainless steel is not that good either because the nickel molecules create bonds with the iron molecules that prevent the iron molecules from moving and aligning with the magnetic field.dan020350 said:I know you can used iron wrapped around with copper coil to create electromagnet , can it be done with steel?

Yes, stainless steel can be used as an electromagnet. However, its magnetic properties are relatively weak compared to other materials like iron or nickel.
Stainless steel can become magnetic through a process called cold working, which involves deforming the steel at a low temperature. This creates tiny regions within the steel that are magnetized in the same direction, resulting in an overall magnetic field.
No, stainless steel is not a good conductor of electricity. It has a low electrical conductivity compared to other metals, which can hinder its ability to function as an electromagnet.
Yes, stainless steel can be used for high-temperature electromagnets. It has a relatively high melting point and good resistance to heat, making it suitable for use in high-temperature environments. However, its magnetic properties may be affected at higher temperatures.
The main advantage of using stainless steel as an electromagnet is its resistance to corrosion. Unlike other materials, stainless steel does not rust or corrode easily, making it a durable choice for long-term use as an electromagnet. Additionally, stainless steel is often readily available and cost-effective.
