Magnetised Iron

Unfortunately, your answer is incorrect.

Iron can be magnetised so that it behaves like a magnet. To do so, a magnet has to interact with the piece of iron in the same way over and over again. Afterwards, it can attract other pieces of iron on its own. You can try this yourself, for instance, with a paperclip.

To understand how the iron changes, it is helpful to answer the following question first:

Why do a magnet and iron attract each other in the first place?

a) Iron reacts to magnets. When coming close to a magnet, the piece of iron itself becomes magnetic, because its inner structure changes.

b) Between iron and magnets, a particularly strong gravity exists, which is far stronger than earth's gravitational pull.

c) The iron and the magnet have a natural eagerness to combine and attract one another.
