What you have here is a classic example of "begging the question". Your question carries with it the implied (but erroneous) statement that water can be magnetized. Neither the hydrogen nor the oxygen which combine to produce the water molecule can be magnetized but, in an intense magnetic field at close to its melting point, oxygen will demonstrate some paramagnetic properties. Magnetized water is a myth but it is used quite frequently to remove money from peoples' wallets.
What else can I help you with?
Is iron a permanent magnet?
No, iron is not a permanent magnet. It can be magnetized in the presence of a magnetic field but will lose its magnetism once the external magnetic field is removed. Permanent magnets, on the other hand, retain their magnetism without the need for an external magnetic field.
How can magnetism be destroyed?
---- Magnetism can be destroyed by following methods:---- * By heating the magnet, * By hammering the magnet.--->In accordance to this point...allowing the magnet to fall violently* By keeping similar poles of magnets together for a long time. * [not sure about this]by keeping magnet under running water.
Why soft iron is used for making a permanent magnet?
Soft iron is not used for making permanent magnets; instead, it is used as a temporary magnet due to its high magnetic permeability and ability to be easily magnetized/demagnetized. Permanent magnets are typically made from hard magnetic materials like neodymium or ferrite, which can retain their magnetism for a long time.
How does a paper clip stick to both north and south poles of a magnet?
A paper clip is neutral or not magnetized and when you bring it to a north or south pole, the opposite little magnets in the clip are attracted to it. If it is kept in contact long enough, the clip will itself become magnitized.
Is a bar magnet a permanent magnet?
A permanent magnet is a magnet which will keep its magnetism for a very long time and is difficult to change. No, As I think a permanent magnet means they have abilities to hold the magnetism when they are magnetized. Such as Alnico permanent magnets, but in fact, they can be demagnetized,such as high temperature, hit each other,pulse waves, out magnetic field influence...What's more, different permanent magnetic material, have different abilities on holding magnetism,they can be used in different environments. you can find some details from some manufacturers website, to learn some knowledges.
Is a magnetized magnet heavier than an unmagnetized magnet?
An unmagnetized magnet is not a magnet. A magnet remains a magnet only as long as it remains magnetic,and ceases to be a magnet when its magnetization is lost.Be that as it may in any event, the state of magnetization of a sample of magnetic material, whether magnetizedor unmagnetized, has no bearing, neither ball nor thrust, on the weight of the magnetic material. In other words,weight is invariant under a transformation of the magnetized state.
Is iron a permanent magnet?
No, iron is not a permanent magnet. It can be magnetized in the presence of a magnetic field but will lose its magnetism once the external magnetic field is removed. Permanent magnets, on the other hand, retain their magnetism without the need for an external magnetic field.
Permanent and temporary magnets?
A temporary magnet is something that has been magnetized that won't stay a magnet for long, such as a paperclip that you have rubbed with a magnet. A Permanent magnet is usually a Lodestone that is found naturally or is manufactured by a company. Permanent magnets are always magnetic.
If a paper clip is picked up by a magnet underwater will the paper clip be magnetized and pick up other paper clips?
Yes. But the attached paper clip will usually not generate a magnetic field as strong as the magnet itself. At some point, either the field will be too weak to pick up another clip, or the weight of the clips will exceed the lifting power of the original magnet. The magnetic field is not affected by water. In fact, the slight reduction in weight due to the buoyancy will normally allow a slightly larger string to be formed underwater than in air.
What distinguishes a permanent magnet from a temporary magnet?
Permanent magnets do not lose their magnetic ability. Temporary magnets, however, gain magnetic properties when they are touched or moved by a permanent magnet. The properties of a temporary magnet dissipates over time after the permanent magnet is removed.
How does something become temporarily magnetized?
if you rub metal up against a magnet for a long enough period of time it will become temporarily magnetized.
Different between temporary magnet and Parmanent magnet?
A temporary magnet can be magnetized or demagnetized easily, while a permanent magnet retains its magnetization over a long period of time. Temporary magnets are usually made of soft magnetic materials like iron, while permanent magnets are made of hard magnetic materials like neodymium or ferrite. Temporary magnets require an external magnetic field to maintain their magnetism, whereas permanent magnets do not.
How can magnetism be destroyed?

When you use a bar to pick up small iron or steel why do you use the end of the magnet?
Magnets have a polarity which is generated by exposing them to a stronger magnetic field during manufacture. They can be polarized through any two faces on the magnet. Typically long skinny magnets are magnetized end to end. Flat magnets are magnetized side to side. Neodymium magnets are relatively strong, and frequently magnetized between flat faces. The magnetic field is very weak on the sides, and very strong at the ends (faces that were polarized).
Can gold stick to a magnet?
Short answer: no. Long answer: it depends.
What is the difference between a soft iron bar and magnet structure?
A soft iron bar can be magnetized temporarily in the presence of a magnetic field and loses its magnetism once the field is removed. A magnet structure, on the other hand, retains its magnetism even without an external magnetic field due to its aligned atomic structure.
What kind of magnet has the same magnetic field as the long coil of wire?
A solenoid magnet, which is a long coil of wire wrapped around a ferromagnetic core, has a similar magnetic field to that of a bar magnet. This is because the magnetic field created by the current flowing through the wire generates a magnetic field similar to that of a bar magnet.
