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.
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.
Rusting of iron needs the presence of water.
Water with oxygen (air). However, only one metal 'rusts' . It is IRON and forms iron oxide (rust). Other metals do NOT rust. They form 'oxides.
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.
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...
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.
Rust is oxidized iron. When iron is exposed to the oxygen in air or water over a period of time, the iron oxidizes. If it is exposed long enough, the iron turns red, grainy and soft and becomes rust. Rust can be removed by sanding or grinding. For a car, this requires multiple sandings with various grits of sanding compound. This is followed by primer, then by paint before new rust has time to set in. If the rust has eaten a hole in the metal, then Bondo is applied first. Once the primer and paint are dry, the metal is protected. Hope that answered your question. Princess

iron goes rusty because it reacts with oxygen and water. When it rains, the iron gets wet. The iron then reacts to sunlight(if there is sunlight) and over time, it rust and the rust gives it a reddish orangish color.
it depends if the nail is put in some place moist surrounded by liquid or just in a dry place
