the process of converting iron to a permanent magnet is called magnetization.
As iron is a ferro magnetic material it is magnetized by applying strong magnetic field across it , this makes the alignment of all the magnetic dipoles present in iron in the same direction .Even after the external magnetic field is removed they retain their arrangement , thus it becomes a permanent magnet

Why the magnetization current is not sinusoidal even though the input voltage is sinusoidal?
In ferromagnetic materials,such as electrical steel,the magnetisation curve is not a straight line,or else the relation B=μH is not linear ( μ is not constant),H is linear function of magnetization current,while B is linear function of input voltage ,so we have : Im=f(μ)U,where f(μ) is not constant,Im=magnetization (magnetizing) current, U=input voltage. I hope this will help.
What is cross magnetization?
In spirituality, cross magnetization occurs when two mediums treat a patient at the same time.In physics, specifically electromagnetism, cross magnetization occurs when the flux-density distribution of the magnetic field that's defining the neutral plane gets distorted by a secondary magnetic field, known as the armature field. This distorting effect, which effectually changes the direction of the neutral plane, is called the armature reaction drop, and is controlled by varying the current through whichever of the two magnetizing devices was designed as the electromagnet.
Is iron a carcinogens?
Iron is not a carcinogen. Iron is a mineral which can be found in a human body. Even iron oxide is not a carcinogen.
What is the main constituent metal in mild steel?
The main element of steel is Iron but has been added with carbon to make steel. The main element of steel is Iron but has been added with carbon to make steel.
What is iron coal and steel?
Iron oxides in nature as it is called iron ore. Is called iron rocks. Magntyt. Hematite.Limonite. Siderite. Steel is an alloy of iron and other compounds that are known.
Is magnetization of iron a chemical reaction?
No, magnetization is not a chemical reaction. Magnetic iron and non-magnetic iron are chemically the same substance. Magnetization is a process of alignment of atomic magnetic fields, which is a purely physical change, not a chemical change.
Is The magnetization of an iron rod an example of a chemical change?
No. Iron is naturally magnetic.
Why is magnetization of iron a physical change?
Magnetizing doesn't involve a chemical reaction.
What is remanence?
The magnetization left behind in a ferromagnetic material (e.g. iron) after an external magnetic field is removed.
What is not a method of magnetization?
There is an endless list of things that are not methods of magnetization. Eating, sleeping, square dancing to mention a few.
What happens to the domains in a piece of iron when it becomes magnetised?
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.
What is demagnetisation?
the process of which the magnetization of a magnet is removed
Which method is used to separate aluminium filings?
magnetization
What are the factors affect the shape of the magnetization curve?
there is no factors
Does the earth's minerals magnetization is the way to earth rotate or fullmoon effect?
Your question is not clear and it is difficult to understand. However the earth's magnetization is not affected by rotation or the full moon.
What is the noun for magnetize?

Can pure iron be separated by a magnet?
Cobalt and nickel are also magnetic elements.
