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).
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.
Exposing a magnet to a DC magnetic field typically won't demagnetize it unless the field is very strong and exceeds the coercivity of the magnet. In most cases, a DC magnetic field won't affect the magnet's strength but can alter its orientation or alignment.
You can demagnetize a magnet by heating it up to its Curie temperature, by striking it with a hard blow, or by applying an alternating magnetic field that disrupts the alignment of its magnetic domains.
There is no scientific evidence to support the claim that magnets can magnetize water. Magnets can interact with water molecules, but they do not magnetize or make water magnetic.
The relative coercitivity of a material helps to magnetize and demagnetised a substance. If the coercitivity id low then the material can be easily demagnetized and vice versa. A substance can be magnetized by creating magnetic filed of opposite charges and demagnetized by creating same filed of charges.
no you can't

magnetize
Yes, you can demagnetize a magnet by subjecting it to high temperatures, hammering it, or exposing it to a strong magnetic field in the opposite direction.
magnetize
The verb form for "magnet" is "magnetize."
duct tape a magnet to it.
You can magnetize a paper clip by passing it repeatedly over a large magnet.

To demagnetize a magnet, you can expose it to high temperatures, pass an alternating current through it, or subject it to strong impacts. These methods disrupt the alignment of the magnetic domains within the magnet, causing it to lose its magnetism.
yes all you have to do is magnetize the iron
Rub the metallic surface with a magnet.
