In a magnetized material, the iron atoms align their magnetic fields in the same direction, creating a net magnetic field. This allows the material to attract or repel other magnets. In an unmagnetized material, the iron atoms have random magnetic orientations, resulting in no net magnetic field.
Contrary to popular belief, most metals cannot be magnetised. The only common metals that can be magnetised are iron, cobalt and nickel. Mild steel, an alloy that contains over 98% iron, can also be magnetised because of its high iron content. Some steels, such as some stainless steels, have larger percentages of other metals which prevent them from being magnetised the same way.
A simple block of magnetized iron is called a magnet.

ferro magnetic substances can be magnetised. but it is not necessary that all the Ferro magnetic substances can be permanently magnetised. it depends on the alignment of domains in the substance.for example wrought iron can be magnetised permanently but soft iron can only be magnetised temporarily(Electro Magnets).
Metals can be magnetised which can produce an attractive force.
In an unmagnetised piece of iron, these magnetic domains are arranged randomly and point in lots of different directions - they cancel each other out. In a magnetised piece of iron, all these domains point in the same direction. This makes one end of the magnet act as a north pole and the other end act as a south pole. The better the domains are aligned, the stronger the magnet. Bye bye!

Yes, every material has its limit in this respect.

none of them. iron can be magnetised but the material itself is not magnetic

Iron is a better core material than steel for applications that require high magnetic permeability due to its higher saturation magnetization. This makes iron cores more efficient in transferring magnetic fields. Additionally, iron cores have lower hysteresis losses compared to steel cores.
Metals can be magnetised which can produce an attractive force.
The iron automatically divides into domains separately. It does not exist in a state when magnetization occurs in the same direction, in the entire material. This is to minimize its internal energy.
If you wrap a length of wire around the iron bar then pass a current through the wire, the bar will become magnetised.
Yes, iron can be magnetized. When exposed to a magnetic field, the magnetic domains in iron align to create a magnetic field of its own. This causes iron to exhibit magnetic properties.
