why is iron magnetic

Pure Iron

It also has outstanding magnetic properties, such as high magnetic saturation, low coercivity, high permeability, as well as excellent conductivity, especially in medium induction ranges. Each cold working process leads to stresses in the microstructure of the material, and thus to a deterioration of its magnetic

Mystery of Moon's Lost Magnetism Explained

Apr 07, 2021A magnetic field is generated by what's called a dynamo, which is caused by the fluid motion of a conducting material, such as liquid iron. In the case of the Earth's magnetic field, this motion occurs in the planet's outer core, and is caused by the convection of heat. But the moon isn't large enough for convection to take place.

Ferromagnetism: Why Is The Earth Core Magnetic?

Ferromagnetism

Iron, nickel, cobalt and some of the rare earths (gadolinium, dysprosium) exhibit a unique magnetic behavior which is called ferromagnetism because iron (ferrum in Latin) is the most common and most dramatic example. Samarium and neodymium in alloys with cobalt have been used to fabricate very strong rare-earth magnets.

Magnetic field of a ferrite core solenoid – zmatt

Jan 19, 2021Why does adding an iron core make a difference? I believe the explanation is that there are "bound currents" at the boundaries of the iron core which also need to be included in any such piecewise calculation of the magnetic field. This stackexchange answer has some good diagrams that help to explain how these bound currents come about.
