Iron. Steel is made of iron. Iron is easily susceptible to molecular realignment which causes magnetism and attraction to it.
Copper is not attracted to magnets because it is a non-magnetic material. The electrons in copper are arranged in such a way that they do not align in a manner that creates a magnetic field. This property makes copper unable to be magnetized or attracted to magnets.
Ferro magnetic materials (those attracted to magnets) have a special arrangement of their electrons which makes them susceptible to magnetic fields. Materials without this special electron structure are not affected my magnets or electric fields in the same way.
the force of objects being attracted by magnets. the coils or solenoids act as magnets and the projectile (which must be able to attract to magnets, often iron or steel is used) is attracted to the coils. but when the projectile reaches the coil the coil must be turned off so the projectile keeps going instead of stopping at the coil.
Certain materials are attracted to magnets because they have unpaired electrons that align in the presence of a magnetic field, creating a magnetic force that pulls them towards the magnet.

Magnets attract when the opposite poles (north and south) come together, creating a magnetic force. This attraction occurs due to the alignment of magnetic domains within the magnets, resulting in a force that pulls the magnets together.
Chalkboards are not magnetic themselves. However, some chalkboards have a steel backing, which makes them magnetic because magnets are attracted to the steel surface. This allows magnetic objects, like magnets and magnetic letters, to stick to the chalkboard.
Normally nickel plating is applied to base metals that aren't attracted to a magnet. At the atomic level the plating itself is attracted but it's such a small amount of the total composition that the entire item won't stick to a magnet. The nickel component of US nickels (and nickel-clad coins such as dimes, quarters, and half-dollars) is so low that the coins aren't attracted for the same reason. Nickel metal makes up only 25% of a nickel coin and 8% of the other coins.
Yes, pig iron is magnetic due to its high iron content. The iron atoms in pig iron are arranged in a way that makes it magnetic, allowing it to be attracted to magnets.
Lots of metals are not very magnetic (everything, even oxygen gas, is a little magnetic ... though some materials are actually repelled by magnets rather than being attracted to them).Materials that are strongly attracted to magnets are called ferromagnetic materials. As the name suggests, iron is one such metal, but cobalt and nickel are also ferromagnetic, and gadolinium is when cold. Some alloys are ferromagnetic and some aren't, but predicting which is which can be difficult, as materials that aren't themselves strongly magnetic may form an alloy that makes an extremely good magnet.Most elemental metals, other than those listed above, are at best paramagnetic (very weakly attracted to magnets). Copper and aluminium are two common examples (the US coin called a "nickel" is only 25% nickel, with the rest being copper, which is why it's not strongly attracted by magnets).
your question makes no sense
Milky magnets makes marrow more meaty :P
