Because aluminum isn't made of metal
Your mechanical valve is made of surgical steel. Magnets are attracted to steel.
because i learned it in class and my teacher told the class that magnets only stick to iron or steel and teachers DO NOT LIE.
Magnets will stick to iron paper clips, but not to plastic ones.
It can. It can be magnetized. Both surfaces can be polished, and they will "ring in". It just has a fairly low coefficient of friction, which is great for moving heavy loads on train tracks... with low energy costs. another input: It can, through the process of "welding"
Yes. if the magnet is powerful enough, the magnets can attract through virtually anything.
No how can that be... if it can stick to steel and steel is meatal than it can stick to metal.
Iron and its alloys (e.g. steel) are attracted to magnets
Because fridges are made of steel.
Steel will stick to magnets, but stainless steel will not.
Because refrigerators are made of steel (iron) even though they have nice finish on the outside and magnets are attracted to steel (iron).
Always did for me, are you sure you haven't confused aluminum for steel?
Refrigerators are made of steel, which is mostly iron, and iron is magnetic.
Your mechanical valve is made of surgical steel. Magnets are attracted to steel.
cork or steel because steel always stick to a magnet and cork somtimes thats all i know about magnets BYE.........

In general, magnets will stick to steel. There are many stainless alloy steels that are non-magnetic, however. Most stainless steels have a metallic crystal structure that gives them few or no magnetic properties.
They stick to other magnets or iron, cobalt and nickel.
