What is the role of the soft iron core?
In a moving coil galvanometer, soft iron core intensifies the magnetic field through it. this causes maximum number of magnetic field lines to pass through the coil.
Why does the soft iron core increases the strength of magnetic field?
Iron core (usually soft iron core) is a highly ferromagnetic material. Ferromagnetic materials allows (and attracts) the magnetic field lines to pass through it. When such a material is used in the electromagnet, the magnetic field lines passing through it increases, thereby, the strength of the electromagnet increases. So my friend, I hope you are satisfied with the answer.
Why do magnets attract to iron but not paper?
Iron has magnetic domains, that tend to align when the iron is in a magnetic field. Many other materials don't have such magnetic domains.
What is the purpose of the soft iron core used in making electromagnet?
The purpose is to enhance the magnetic field - to make it stronger - compared to just using air.
When you placed the magnet next to the iron?
nothing will happen dumbazz because it isnt magnetic
If a soft iron core is Inserted into a solenoid will the strength of magnetic field produced by it change?
It has been found that if a soft iron rod called core is placed inside a solenoid, then the strength of the magnetic field becomes very large because the iron core is magnetized by induction The core of the electromagnet must be of soft iron because soft iron loses all of its magnetism when current in the coil is switched off or stopped

Why is a soft iron core used in a relay coil?
because it can magnetize and demagnetize easily
What is the definition of magnetic keepers?
A magnetic keeper is a strip of soft iron or steel which is placed across the poles of a permanent magnet to help preserve the magnetism.
Can electro magnet magnetize and demagnetize soft iron?
Yes, they can magnetise soft iron. Not sure about demagnetising though. I assume that if more than one or two were placed around the soft magnet, it could demagnetise it.. However, the soft iron would need to be 'hit' so that the poles in the iron can allign with the magnetic fields due to the electro magnet.
Is iron a magnetic?
Yes, iron is magnetic.
What is the magnetic character for iron?
the answer is the iron of magnetic field so that it can cause magnetic field... iron.
Why is iron a soft magnetic material?
Because pure iron can gain or lose a magnetic field very quickly. A hard magnet (certain steels) will hold its field indefinitely (unless heated to too high a temp).
How do you make permanent magnets?
A permnent magnet generally made by soft iron. When we put a core of soft iron in a strong magnetic field, by induction it's made permanent magnet.just superheat a peice of iron and put it in a precence of a strong magnetic feild and let it cool slowly(be sure to heat it enough so it glows red hot)
What are hard and soft materials?
The magnetic materials which can magnetise and de-magnetise easily are called "soft magnetic materials" example:-ferrites,iron-cobalt alloy. The magnetic materials which cannot magnetise and de-magnetise easily are called "hard magnetic materials" example:-aluminium(al),nickel-cobalt alloy.
Which types of iron are not magnetic?
All iron is magnetic.
