Not usually, but it can be magnetised.

using a magnet: steel atracts and aluminum doesn't
A magnet
because a reed switch is like an electromagnet so the purpose of it is that it will spring open when you remove the magnet. Iron is better because it looses it's magnetism quicker, whereas steel strips don't loose their magnetism as quickly so when you do remove the magnet, a steel strip would stay closed for a while longer rather than open straight away :D
The word "magnet" is a name for an object with the physical property of magnetism and is not necessarily chemically descriptive. Elemental iron can be magnetized, but is not necessarily magnetic. Mixtures such as carbon steel and many metallic alloys can also be magnets, as can compounds such as magnetite, which has the chemical formula Fe3O4.
This effect has nothing to do with the magnet sticking to the side of the copper. Magnets will only stick to ferromagnetic substances such as iron and steel, not copper. The actual physics of this experiment is more subtle. The magnet falling down the tube results in a changing magnetic field within the copper tube. This changing magnetic field produces a current within the tube. That current creates a new magnetic field within the tube which slows down the magnet.
Steel will stick to magnets, but stainless steel will not.
To remain a magnet it has to be made out of steel as steel makes a permanent magnet.
Either pole of a magnet can attract steel.
If the wheels are steel, a magnet will stick. If aluminum, it will not.If the wheels are steel, a magnet will stick. If aluminum, it will not.
it wouldn't be magnet to a aluminum nail because the aluminum is not a way of magnet and a steel nail would because steel is a way of magnet.
A scrap heap magnet attracts steel - but not steel with a high chromium or nickel content
That depends on the steel. If it is a ferrous steel the magnet (either North or South) will attract it - If it is a a stainless steel that is austenitic steel it will not.
Use a magnet. Brass is non ferrous and will not be attracted to the magnet.
No it can't become a magnet.
probably
The EFFECT of steel passing over a magnet can be detected and therefore recorded.
Put the magnet back on the fridge.Kevin liked to play with a magnet.
