Rusting is accelerated in wet environments.
Yes Iron ( Fe has the liability to rust when in contact in water, the reaction erupts the iron to rust.
Rusting of iron needs the presence of water.
Wrought iron will like most irons rust unless it is properly maintained for, by this i mean keep a fresh coat of paint on it, preferrably a "Rustoleum" type and every few years wire brush any rust spots and repaint the entire surface on a nice dry day to keep it rust free.
Yes, wrought iron can rust easily due to its iron content. To prevent or mitigate rusting in wrought iron materials, methods such as applying a protective coating like paint or a rust-resistant finish, regular cleaning and maintenance, and keeping the iron dry can be effective.
Cast iron can rust when exposed to moisture and air. To prevent rusting, make sure to dry the cast iron thoroughly after washing, season it regularly with oil, and store it in a dry place.
An iron nail would not rust while in a drying agent because drying agents are used to remove moisture from a substance, which is necessary for the oxidation process that causes rust. By keeping the nail dry, the conditions for rust formation would be prevented.
Rust is oxidized iron (aka Ferric Oxide, or FeO2), or iron that has been exposed sufficiently to oxygen. It can take anywhere from hours to form in a damp or wet environment, to years in a dry one.
Iron can still rust in an air conditioned room if there is moisture present in the air. Air conditioning can reduce humidity levels, but if the room is not well-sealed or if there are other sources of moisture, rust can still occur. It's important to keep iron objects dry to prevent rusting.
You need really fine iron powder; a fine file and somthing out of iron you can file. Then a liquid to keep the iron in suspension; it should dry (evaporate) but not too quickly- water will work if you use your ink right away- if you wait the iron will rust and rust is not as magnetic as pure iron...
Dry iron filings and wet iron filings have different physical properties. Dry iron filings are free-flowing and easily spread out, while wet iron filings clump together due to the presence of water. Additionally, wet iron filings may rust more easily due to the moisture content.
To clean cast iron use hot water and a cloth or sponge. Dry the cast iron right away. You should not use soap, and you should never soak cast iron or it will rust.
Most likely the cable is dry inside or kinked. It will form rust and get hung up as it rotates causing the jumpy needle.
