Iron/steel magnetic properties

[bluechipx]

Is iron/steel magnetic at temperatures over their melting point? I have an idea, but it will only work if ferrous materials retain magnetic properties in a liquid state.

 

[Dr Lots-o'watts]

Melting temperature of iron : 1811 K
Currie temperature of iron : 1043 K

From wikipedia:

"When the temperature rises beyond a certain point, called the Curie temperature, there is a second-order phase transition and the system can no longer maintain a spontaneous magnetization, although it still responds paramagnetically to an external field."

Iron and steel are both ferrous materials, meaning they contain iron as the main component. Iron is known to be magnetic, and steel, which is an alloy of iron and carbon, also exhibits magnetic properties.

However, when it comes to temperatures above their melting points, the magnetic properties of iron and steel may change. At high temperatures, the atoms in these materials are in a more disordered state, which can disrupt the alignment of their magnetic domains. This can cause a decrease in their magnetic strength or even a loss of magnetism altogether.

In general, iron and steel lose their magnetic properties at temperatures above their melting points. However, there are some exceptions to this rule. For example, some types of steel, such as austenitic stainless steel, can retain some degree of magnetism even at high temperatures.

Therefore, while it is not a universal rule, it is safe to say that iron and steel are not typically magnetic at temperatures above their melting points. This may affect the success of your idea, depending on the specific properties and composition of the ferrous materials you are working with. It is always important to consider the effects of temperature on the magnetic properties of materials in scientific experiments and applications.
