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).

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.
Will exposing a magnet to a DC magnetic field demagnetize it?
Obviously no.
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.
How do you demagnatise a magnet?
You can demagnetize a magnet by: -dropping it many times -heating it over a flame -hammering it many times
Which side of the magnet do you use to magnetized water?
You can't magnetize water, it's a myth.
Can you demagnetize a magnet with a magnet?
no you can't
What are the ways of demagnetize the magnet?
By keeping them in magnet keepers
Why is a permanent magnet hard to magnetize?
You cannot magnetize a permanent magnet because it is already magnetized.
What is the verb of magnet?
magnetize
What is the verb form of magnet?
magnetize
How do you magnetize a magnet?
keep striking it in one direction by another magnet
How do you magnetize sockets?
duct tape a magnet to it.
Which of the following can be done to demagnetize a permanent magnet?
heating the magnet past the Curie point
How do you put magnetize in a sentence?
You can magnetize a paper clip by passing it repeatedly over a large magnet.
What is the thing that weakens a magnet?
Magnets are "demagnetized" by extreme heat. If you boil a magnet in water, the heat will demagnetize the magnet.
