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.
What else can I help you with?
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?
Core
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.
Why are some iron objects magnetic and others not magnrtic?
If the iron atoms are aligned then the object is magnetic, if they are randomly oriented then it is not. How the object was manufactured may be the cause of the difference, but it always possible to intentionally either magnetize OR demagnetize an object.
Can iron be made permanent by stroking it with a strong magnet?
No, iron cannot be made permanently magnetic by stroking it with a strong magnet. This process can only magnetize the iron temporarily. To create a permanent magnet, iron needs to be exposed to stronger magnetic fields or undergo specific treatment processes.

Can a magnet be made from iron?
yes all you have to do is magnetize the iron
How can I magnetize iron?
To magnetize iron, you can rub a magnet along the iron in one direction multiple times. This will align the magnetic domains in the iron, making it magnetic.
What types of magnets are produced by running current through a soft iron core?
When current is run through a soft iron core, an electromagnet is produced. This type of magnet can be turned on and off by controlling the flow of electricity. Soft iron cores are often used in electromagnets because they can quickly magnetize and demagnetize.

Which mixture would correctly separate sand and iron?
Iron can be separated from sand using a (electro)magnet.
Why efficiency of dc machine is high when it works as generator compare to motor?
dc generators and motors and generators can be constructed from solid iron ac generators MUST be made of laminated iron to reduce eddy current losses that aside a dc electro magnet if left on for a short time tends to make the iron into a temporary magnet if in a scrapyard or a magnetic chuck on a grinder it will have some method to demagnetize the iron so it can let go ac motors, magnets, transformers must magnetize and demagnetize the iron 120times every second. the power loss shows up in the iron as heat iron steel borosilicatesteel these losses can be decreased the insulation on the laminations can be improved the losses can be as low as 3% and with modern materials in practice it seems to be 6%-15% ac has this loss dc does not a generator you turn the shaft a motor you apply electricity entirely reversible processes and the loss is the same in either

What happens to the iron ruler if it rubs with a magnet?
It will become an electro-magnet which is an temporary magnet. it is because of the induction property, the magnetic effect gets transfered to the Scale. (it can be any piece of Iron)
Can iron be made permanent by stroking it with a strong magnet?
No, iron cannot be made permanently magnetic by stroking it with a strong magnet. This process can only magnetize the iron temporarily. To create a permanent magnet, iron needs to be exposed to stronger magnetic fields or undergo specific treatment processes.
