why are tin cans attracted to magnets?
607323
Tin is paramagnetic—it is very weakly attracted to a magnet. Diamagnetic materials are weakly repelled. ... They are very strongly attracted to magnets and greatly amplify magnetic fields that pass through them.

Tin is relatively rare, and modern cans are usually made of aluminum or other treated metals. While tin is technically considered a "common" metal instead of a precious metal like gold, tin is still rare. It may be the least available of all common metals.

Like any electricity, this creates an electromagnetic field that naturally attracts magnetic materials like iron. ... Several aquatic animals -- such as sharks, skates, salmon, sea turtles and lobsters -- may use the Earth's natural magnetic fields like a compass to navigate and detect their prey.

Steel Cans and Tin Cans (soup cans, veggie cans, coffee cans, etc.) Most people call them "tin cans," but the containers your green beans come in are mostly made of steel. ... Steel is magnetic, and aluminum is not. Steel cans make up about 90% of the U.S. food can market.

will a magnet attract any metallic object, such as those made of aluminum or copper? ... the strong magnet, and vice versa, which creates the attraction. two iron bars attract each other no matter which ends are placed close together.

Magnets have the ability to attract certain metals like iron and steel. Metal paper clips are made from steel and should be attracted by a magnet. ... Hold the magnet at the same level as the paper clip but about 30 cm away.

Unlike a magnet's effect on metals and other magnets, magnetic fields don't attract or repel ions, but they can deflect ions under certain conditions. The ions must not only be moving, they must move on a path perpendicular to the magnetic field.

Neodymium magnets are lighter and smaller than other magnets, making them a perfect choice for earbuds and headphones. ... Neodymium magnets produce a higher sensitivity and substantial sound output using less power to do so.

Steel cans are made of tinplate (tin-coated steel) or of tin-free steel. In some dialects, even aluminium cans are called "tin cans".

Tuna Cans. Some small tuna cans are made out of aluminum, and also recycle easily. ... If the magnet sticks, it is not aluminum but steel. If the can is steel, it should be placed into your steel can recycling bin if available.

When a magnet goes near a special kind of metal or other magnets, and the poles (sides) touching are opposite, it will pull, or attract the other metal or magnet closer. Also, if the two poles are the same, the two magnets will push away, or repel, from each other. This is called magnetism.

Tin is very soft and malleable, ductile with low tensile strength. It's often used to coat steel to prevent corrosion. Tinplate steel is used to make tin cans to hold food.

The short answer is yes, but only because the size of a magnet means that there are proportionally more domains that can align and produce a stronger magnetic field than a smaller piece of the same material.

['Paramagnetic materials. The materials which are not strongly attracted to a magnet are known as paramagnetic material. ... ', 'Diamagnetic materials. The materials which are repelled by a magnet such as zinc. ... ', 'Ferromagnetic materials. ... ', 'Ferrites.']

Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include the elements iron, nickel and cobalt and their alloys, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone.

Nearly all tin cans are plastic lined with epoxy resin. Epoxy resins, are used because of their “exceptional combination of toughness, adhesion, formability and chemical resistance. These coatings make it possible for food products to maintain their quality and taste, while extending shelf life.

As you've discovered, aluminum cans have a polymer coating on the inside of the can. When the file is used to scrape away the polymer coating, the aluminum metal is exposed. The aluminum reacts with the copper (II) chloride solution and an electron exchange takes place.
