no, they can be shaped like U's circles, rocks and varios other shapes
Electricity affects magnetism because it can determine the direction of a current. A number of magnets are just iron bars with an electric current circulating around it.
Magnets is made of iron. Magnets are attracted to anything made out of iron.
magnets detect iron because of the magnetic feild in the magnet which atracts iron to stick to it.
Iron cobalt, nickel and their alloys are magnetic; magnetic bars for stirrers, magnetic bars for maximum-minimum thermometers, magnetic souvenirs, etc. are examples of magnets.
Magnets.
Magnets have both a north and south pole, they attract materials such as iron and steel, and can create a magnetic field around them.
Magnets are attracted to anything with iron in it. Rust is Iron Oxide, so yes!
you can use magnets to separate iron from sand.
It would be more accurate to say that magnets attract iron (but under the Newtonian principle that for every action there is an equal but opposite reaction, if magnets attract iron, then iron attracts magnets, so yes).
Yes, magnets can stick to wrought iron because it contains a small amount of ferrous material that is attracted to magnets. However, wrought iron is not as magnetic as steel, which contains a higher percentage of iron.
it does
They stick to other magnets or iron, cobalt and nickel.
