It will stop rusting because of something called cathode protection. Because the magnesium is more reactive than the steel the electricity need to cause oxidation is drawn to the magnesium leaving the steel unable oxidize. The same principle is used on large ships. I you look at a cruse ship or a tanker you will see large blocks on the outside of the hull that most people think is to keep the side of the ship from hitting when they dock, but they actually protect the hull of the ship in the same way.

Why is Zn used to coat steel roofs and not magnesium?
Zinc is suitable for coating steel roofs because zinc does not react with water. It thus prevents the steel roof from rusting since steel is basically iron plus carbon and it will rust in the presence of oxygen and water. Furthermore, zinc is more reactive than iron, and can thus act as a sacrificial metal and corrode in place of iron, in the event that the zinc coating is damaged and the iron is exposed. On the other hand, magnesium is an alkaline earth metal and is too reactive. It will react with water to form magnesium hydroxide. (However, this reaction takes place for only a short while because the magnesium hydroxide produced is insoluble and will coat the metal, preventing further reaction between magnesium and water.) Mg + 2H2O → Mg(OH)2 + H2
Can chlorine rust?
No, rusting is a term reserved for the oxidation of iron or iron alloys. Processes similar to rusting involve the oxidation of other metals. Although chlorine can be oxidized, it is not considered rusting when it happens, especially considering that chlorine is a nonmetallic gas.
How quickly does steel rust when exposed to the elements?
Steel can rust relatively quickly when exposed to the elements, especially in moist or humid conditions. The rate of rusting can vary depending on factors such as the type of steel, the presence of corrosive substances in the environment, and the level of exposure to moisture. In general, steel can start to show signs of rust within a few days to a few weeks when exposed to the elements. Regular maintenance and protective coatings can help slow down the rusting process.
Does iodine rust?
No, iodine does not rust because rusting is a specific type of corrosion that occurs only in metals, particularly iron and steel, when exposed to oxygen and moisture. Iodine is a non-metallic element that does not exhibit rusting behavior.
What types of metals do not rust?
I think that srtonger metals like gold do not rust. I also think that some metals, when combined with others do not rust, like when you combine iron with aluminum, it doesn't rust. By definition, the only metals that rust are iron and iron alloys. Even so, not all iron alloys rust. Stainless steel (an iron alloy) does not rust. Gold doesn't rust, in that it doesn't combine with oxygen from the atmosphere to form a surface of gold oxide. But it can tarnish, that is, for a thin transparent darker layer to form on the surface. however steel will rust. to protect a metal from rusting you must galvanzie it or paint. for example to galvanzie iron you must use a metal higher in the electrochemical series like zinc. this will protect it from rusting.
Why does attaching blocks of magnesium to steel pipelines prevent them from rusting?
Magnesium is a stronger reducing agent than iron. The magnesium has a stronger tendency to take up the oxygen to form magnesium oxide than iron. Iron misses out on the oxygen until the magnesium is all used up.
What is the definition of the word galvanize?
To galvanize means that one is applying a protective layer of zinc on top of a product made of steel or iron. This prevents the steel or iron from rusting.
Can you use black coated knife with magnesium sticks to make a fire?
If you use a knife as your striker for a magnesium block or rod, you need to use the back of the blade, and it has to be made of carbon steel. Any type of coating on the blade that prevents contact of carbon steel with the magnesium block's flint rod prevents it from making sparks.
Rusting of steel is?
A good example of an oxidation reaction. The rusting of steel is essentially just rusting (oxidation) of iron.
How effective are steel castings at preventing rusting?
Steel castings can prevent rusting depending on what the kind of steel. Carbon steel may cause rusting at a higher rate than stainless steel.
What is galvanized steel an alloy of?
Galvanising is the process of application of zinc coating on steel surfaces. It prevents steel surface from rusting.
Why is a ball given in the gauge glass?
incase if boiler gauge glass breaks...this steel ball fits on the tube and it prevents of leakage of water.
Which metal prevent the rusting of iron?
Stainless steel, which contains chromium, nickel, and other elements, is commonly used to prevent the rusting of iron. The chromium in stainless steel forms a protective oxide layer on the surface of the metal that helps to prevent corrosion.

Corosion of steel is known as?
Rusting.
What example of a metal is rust proof?
Stainless steel is an example of a metal that is rust-proof. It contains chromium, which forms a protective layer on the surface of the metal that prevents it from rusting.
Will steel wool corrode in water?
The simply answer is yes. Steel wool does not have a coating that will protect it from rusting in water. But rusting will take some time.
