It disrupts the alignment of the North and South poles.

You really messed up you used full-strength bleach to clean ceramic floor Now they are very dull and you are still trying to remove the smell Any suggestions?
To make it clean: Try scrubbing it with a mixture containing; the bleach you used and a cup full of water. If that doesn't work...buy another bleach! To remove the smell: Add any liquid scented soap to water and put a drop of bleach in...just a drop!! Thoroughly scrub the mixture all over the floor, now you will have a sweet smelling floor!
What happened to a semen if you drop in red or blue litmus paper?
Sperm is slightly basic; red litmus become blue.
What happens if you put nitric acid and glycerin in a jar and then drop the jar on the kitchen floor?
The jar explodes immediately. Obviously, nitric acid mixed with glycerine is nitroglycerine (which is powerful explosive).
How do you separate a mixture of gold nuggets from iron filings and sodium?
The separation of gold from iron filings and sodium metal (a dangerous substance which will react with water in the air) could be done in two steps. Take a magnet and put it inside a plastic bag. Carefully and fully move the bagged magnet over the mixture, gently stirring it to insure the magnet can "reach" all the iron filings. When you are done, lift the magnet clear of the mixture, and you should have all the iron filings stuck to the magnet, which is inside the bag. If you carefully "invert" the bag, you'll then have the bag around the filings, which will still be stuck to the magnet with a layer of plastic bag between the two. Then just close the bag and remove the magnet. Your iron filings have been separated and bagged up. Now turn your attention to the gold and sodium mixture. Put them in a big heavy plastic container. If you *carefully* add water, you will get a chemical reaction. It is *critical* to put water in a drop at a time. (Yes, a drop at a time.) The sodium will react with the water and create sodium hydroxide, which is powerful base. It will also create a lot of heat, so you have to take all day to drop in the water so it won't melt your bucket. There will be some strong fumes, too, so take precautions. The bucket, because it is plastic, won't react with the sodium hydroxide. After you spend all day dripping the water into the mixture to react with all the sodium, you'll have a solution of sodium hydroxide with the gold in it. Strain this mixture and the gold will remain in the sieve. You'll need to wear a ton of protection to perform this evolution. Rinse your gold well to remove the traces of the sodium hydroxide and you're in business.
What is the effect of magnetic field on aluminium?
Aluminum is non-magnetic, but does interact with magnetic fields. Aluminum isn't normally magnetic, but as you carry a large aluminum tray towards the magnet, you find that the magnet repels the aluminum, why? Lenz's law. The magnet induces a magnetic field in the moving aluminum tray to oppose it's own, effectively pushing it away. As long as the tray doesn't move, it experiences no magnetic forces. But when you drop it, it falls past the magnet remarkably slowly. When the tray is stationary the magnetic field is not changing, but as soon as it moves, the field begins changing and an opposing field is induced. If you want to test this, and you should, because it's cool, find a rare earth magnet and an aluminum tube. Drop the magnet into the tube and watch how it takes many times as long to fall through. Also look up eddy currents on aluminum, they can be produced by spinning a magnetic field, and shoots aluminum cans off of conveyor belts.
Why should you not drop magnets on floor?
It might damage the floor, and it might damage the magnet.
If you drop a magnet it will?
If you drop a magnet it will hit the object under it
Why should you never drop a magnet on the floor?
It will lose its magnetic field. The vibrations made from the drop charge the electrons and make them move out of the line that they were in, this causes the magnet to lose its magnetism.
What might happen if you drop a permanent magnet or strike it hard?
A permanent magnet may become unmagnetized because a shock it will have.
What demagnetize a magnet?
Drop it on the floor a few times.Hit it with a hammer a few times.Heat it red hot in the stove flame.Wrap several turns of wire around it and run a high AC current through for a while.
What can demagnetize a magnet?
Factors such as heat, strong vibrations, exposure to other magnets, or physical impact can demagnetize a magnet by disrupting the alignment of its magnetic domains. Additionally, heating a magnet past its Curie temperature, which varies depending on the material, can cause permanent demagnetization.
What will happenis you drop a copper ring around a magnet?
They get Atracted
Can heating or hitting a permanent magnet ruin it?
When you heat a magnet past its' Currie point the domains become unaligned. Same when you drop it.
What is a scrapyard magnet?
a scrap yard magnet is an electro magnet used to pick up bits of metal. this is used because it can drop the metal because it can be turned on and off
What would happen if you hit or drop a magnet?
it loses its magnetic properties
When you drop a magnet into a bucket of sand the magnet has a preference of which pole hits first Has this something to do with cats?
YES it alternates their ovulating sequence!
If you drop a sponge on the floor, is the sponge dirty or is the floor clean?
To be completely honest it depends on if your floor is dirty or not. If your floor is really dirty then the sponge is dirty. but in order for your floor to be clean when u 'drop' a sponge you have to apply elbow grease to clean it.
