No it wont but if the water is hot then it will lose its magnetism

Can a magnet pass through water?
The magnet should be able to extract iron out of water as water and iron are not chemically combined. If the water and iron would have chemically combined then it would be futile to separate them using a magnet. Note that the stronger the magnet the more iron will be removed from water.
What is thebest method to separate paperclips from a mixture of salt and pennies?
One way to separate paperclips from a mixture of salt and pennies is to use a magnet. The paperclips will be attracted to the magnet and can be easily picked up, while the salt and pennies will remain unaffected. Alternatively, you could dissolve the mixture in water, as the paperclips will sink, while the salt will dissolve and the pennies will remain at the bottom.
Will water weaken a magnet?
Water can temporarily weaken a magnet by disrupting the magnetic force between its molecules. However, once the water is removed and the magnet is dried thoroughly, its magnetic strength should return to normal. Prolonged exposure to water can cause rusting and permanent damage to the magnet.
How many electrons does magnetism have?
Magnetism and Electricity are two totally different things . Electricity is the movement of electrons in an electrical conductor (usually Copper or Aluminium) Magnetism exists as a stationary force field surrounding a magnet which has all of the stationary electrons in the magnetic material, all pointing in the same direction. Electrons cannot be counted and nobody has any need to count them. (Just as we have no need to count the quantity of molecules in a stream of water in a pipe.) We only measure the EFFECT of electrons when they flow in a wire. it is called 'Current". With magnetism we measure the strength of a magnetic field, which is a stationary thing . Field strength is measured in 'Oersted'.
Can magnetism pass through nickel?
Basically...Yes! it is a type of metal magnetism can pass through various liquids such as water other examples include metal,copper and iron Magnetism can pass through nearly all types of materials which are non-magnetic>they include glass and paper. Usually magnetic materials conduct heat easily> an electro-magnet is,in layman terms,a magnet which can be turned on and off it turns on when a power source,usually a battery,runs electricity through it,activating it,and turns off when the power source is deactivated>it is commonly used in door bells magnets can spoil when they are dropped or heated. i hoped i answered your answer :)
How can magnetism be destroyed?
Magnetism is a fundamental force of nature that cannot be destroyed. However, materials that are magnetized can lose their magnetism if exposed to extreme heat or a strong magnetic field in the opposite direction, causing the magnetic domains within the material to become disordered.
How can 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 wont a magnet help you separate a mixture of salt and water?
A magnet is not effective at separating salt and water because salt is not attracted to magnets. The components in the mixture have different physical properties (magnetism for the magnet, solubility for the salt) that make it impossible to separate them using a magnet. You would need to use methods like evaporation or filtration to separate salt from water.
What happened if magnet dipped in salt?
if a magnet gets dipped is salt it loses some magnetism this can be experimented if you put iron filings in a plastic cup filled with water, you will see the water loses its magnetic field and wont see much movement at all.
Why are strong magnets attracted to a door magnet in a bowl of water then three metal thumbtacks?
The strong magnet is attracted to the door magnet because opposite poles attract each other - the door magnet was likely oriented to attract the strong magnet. The metal thumbtacks are not attracted to the strong magnet because the magnetism of the thumbtacks is weaker compared to the door magnet.
What happens if a magnet gets wet?
Yes, a magnet will work under water. To cite one example, a magnet on a string out on the docks is sometimes used to retrieve car keys that tourists sometimes accidently drop into the water.
Explain how you can use physical properties to separate filings from sawdust?
You can use a magnet to separate iron filings from sawdust since iron is magnetic while wood is not. Simply pass a magnet over the mixture to pull out the filings. This method takes advantage of the physical property of magnetism to separate the two materials.
Can a magnet pick up a paper clip in water?
Certainly, as long as the paper clips are made of iron or steel. Most paper clips are made of polished or zinc-plated steel. Magnetism is a field that is not affected by water or any intervening matter unless that matter is also magnetic, or ferromagnetic.
Would magnets attract to a paperclip under water?
Yes, magnets can still attract to a paperclip under water. Water does not significantly affect the magnetic force between the magnet and the paperclip.
What is blanching point?
Blanching means putting the food in boiling water for 1 or 2 minutes.
Can you de-magnetise a magnet by putting it in hot water?
Sort of. Magnets become weaker with heat, but boiling water is not enough to completely demagnetize unless it was a very weak magnet to begin with. It will become weaker, but the only fool-proof way is to make it borderline molten, completely randomizing the domains.
How long should you wait till you put your goldfish in to the water after putting aquasafe in the water?
As long as the water temperature of the new water is the same as the old water, it is ok after about 5 minutes.
