It's possible. Magnets usually have a good deal of iron in them, particularly the older ones. Iron can rust or otherwise be attacked, depending on the conditions under which it is stored. Magnets are generally suseptible to corrosion.
typically black and the corrosion products tend to flake off and crumble to dust (which is a severe inhalation hazard)
Put a small amount, just enough to be consumed in a few minutes, into the tank. For fries, crumble up the food if it is a flake, like TetraColor.
Iron can corrode and weaken when it rusts, but it does not crumble like some other materials. The rust forms on the surface of the iron, causing it to flake off in layers over time. This can eventually lead to structural integrity issues if left untreated.
The strength of magnets can change over time due to factors like temperature and physical damage. Magnets can lose their strength as they age, but the rate of decline varies depending on the type of magnet and its usage.

A flake is a small, flat piece that falls off of a larger object. When used as a verb, flake means to break off in small pieces or layers. In slang terms, someone who is unreliable or unreliable can be called a flake.
