dose a magnet lose its magnetism when its put into water? plz help, i really need 2 know by Sunday! Thanks!?

Answer 1

No, magnets are just as effective under water as they are out of water. Water has barely any magnetic force, and the tiny tiny tiny amount that it does have is not significant - therefore it will not affect the magnetism of the magnet.

Answer 2

The old professor says: No. Not in the short run. If left in the water long enough, the magnet could rust and lose its magnetic properties as it changes to Fe2O3...which is a non-magnetic mineral. There are many uses for magnets underwater. During times of war, magnetic mines were stuck on the sides of battleships...and some were put in floating minefields only to be drawn towards any steel hulled boat passing by.

Answer 3

This is what Wikipedia had to say:

Demagnetizing materials
Permanent magnets can be demagnetized in the following ways:

Heating a magnet past its Curie point will destroy the long range ordering.
Contact through stroking one magnet with another in random fashion will demagnetize the magnet being stroked, in some cases; some materials have a very high coercive field and cannot be demagnetized with other permanent magnets.
Hammering or jarring will destroy the long range ordering within the magnet.
A magnet being placed in a solenoid which has an alternating current being passed through it will have its long range ordering disrupted, in much the same way that direct current can cause ordering.
In an electromagnet which uses a soft iron core, ceasing the flow of current will eliminate the magnetic field. However, a slight field may remain in the core material as a result of hysteresis.

Also, if you need to know, why don't you just get two magnets and throw them in the water and try it out?

Answer 4

No, not in the least. Going fishin'? A common application for permanent magnets is to tie them to a rope and retrieve steel objects that have falled into water. In fact, the weight (in air) of an object that can be lifted in this way is actually increased due to the partial bouyancy that results from the object being submerged.

Answer 5

Water is very almost thoroughly non-magnetic, so bearing directly to comparable to while they are interior the air. That stated, as long as there is atomic vibration, the guy atoms interior the magnetic domain names can replace into un-aligned and, for this reason, the magnetic capability decreases needless to say by using the years. Magnets is often remagnetized as quickly as they lose their capability.

Answer 6

No, the magnetic fields of a magnet are not affected by water.

Answer 7

No, it does not. Of couse, a simple test of this would be to put a magnet in a glass of water, and put another one outside the glass. When this is done, it is clear that the maget is still magnetic.

Answer 8

No
