the aluminum cans don't attract and and steel attracts because its is made of iron and aluminum is not.
A 'tin can' is actually made of steel, which is a magnetic alloy of iron. There is sometimes a layer of tin (or zinc), electroplated onto the surface, so the name is misleading. It is more properly a 'tinned' can as it is a steel can which has been 'tinned' to stop it from corroding.
Magnets will pick up steel cans, lifting them away from a solid waste stream. Additionally, rapidly changing magnetic fields can be used to "pop" other metals out of a solid waste stream, through current induced in those metals.
A magnet can sort the ferrousmetalse.g., iron and steel, from the feed stream.

Car wheels are made of pressed steel or molded aluminum-magnesium alloy. Most other land vehicles use steel wheels of some sort.
They are made of several different metals, including steel, copper, aluminum and silver. Many are made of some sort of core (steel, copper, gut, or various plastics) and then wrapped with aluminum or silver. Often the upper two strings (A and D) are steel, wrapped with aluminum or silver, and the lower two (G and C) are gut or perlon wrapped with aluminum or silver. Try different types of strings to find the sound and feel you like best.
Steel is separated from other metals in scrap yards using a combination of physical and magnetic methods. Since steel is ferromagnetic, powerful magnets can attract and isolate it from non-magnetic metals like aluminum and copper. Additionally, processes such as shredding and screening can further sort materials based on size and density. Advanced techniques, like eddy current separators, may also be employed to enhance the separation efficiency.
A metal roof is roofing material made out of some sort of metal. Most commonly steel but also available in copper, aluminum, and zinc.

You can use an electromagnet to sort cans by activating the magnet to attract ferromagnetic cans while non-ferromagnetic cans remain in place, allowing for separation based on material composition. By varying the strength of the magnetic field or controlling the activation periods, you can fine-tune the sorting process to efficiently separate cans made of different materials.
A needle made out of steel - the sort you sew a button on with.
im not sure but i think magnets of some sort
