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.

How do you magnetize and demagnetize a magnet?
By placing Iron in a strong magnetic field, the field will turn the iron into a magnet. If you melt the iron and then allow it to resolidify, it will drop the magnetic charge (and you can charge it again if you wish).
What c is the piece of iron inside an electro magnet?

How are electro magnet different from permanent magnet?
Electro magnets differs from permanent magnet because it requires electricity. A simple electro magnet consists of an iron rod wrapped in a coil of copper and when electricity flows through the copper, a magnetic field is formed.
Fe separated from Al physically?
Iron can be separated with an (electro)magnet.
What factors would affect the strength of the temporary magnet?
It depends on how you magnetize the temporary magnet.Material: Hard steel are harder to magnetize but harder to demagnetize compared to soft iron, so depending on duration, hard steel might be better (the longer the duration the better hard steel will be)Strength of original magnet (by induced magnetism): Of course, the stronger the first magnet, the more magnetism will be transferred.Number of coils (by electromagnetism): The more the merrier of course, where more coils mean more current flowing through (or around) it.

Can a magnet be made from iron?
yes all you have to do is magnetize the iron
How can a non magnetic nail be magnetised?
Typically you can magnetize iron or steel by exposing it to a strong magnetic field. Common "ceramic" magnets may not be strong enough, but you may need a strong rare earth magnet or a strong electro magnet.
What is ferromagnetnetic?
A material which may be magnetize or convert into magnet, it is derived from ferrium means Iron.

Is there such a thing as a round magnet?
Magnets can be in any shape. You can have a sphere of iron and magnetize it. I don't believe it is commonly used in practice, but it is certainly possible.Magnets can be in any shape.

How can you magnetise an iton needle permanently using a strong bar magnet?
You magnetize an iron needle permanently by stroking it with a strong bar magnet.

Why is an armature made of iron?
so the electro magnet can attract it as it will be magnetic

Earth is what kind of magnet?
Its an electro-magnet - currents flowing through the iron core.
