Why do non-magnetized iron nails attract to a magnet?

When a non-magnetized iron nail is brought close to a magnet, it is attracted to the magnet. This is because the iron nail is made up of tiny magnetic domains that align themselves with the magnetic field of the magnet, causing the nail to be attracted to it.

Iron is a ferromagnetic material, which means it can be easily magnetized. In its natural state, the iron nail is not magnetized, and its magnetic domains are randomly oriented. However, when a magnet is brought close to the iron nail, the magnetic field of the magnet aligns the magnetic domains in the iron nail in the same direction as the magnet's field. This alignment creates a temporary magnet in the iron nail, causing it to be attracted to the magnet.

The strength of the attraction between the magnet and the iron nail depends on various factors, including the strength of the magnet, the distance between the magnet and the nail, and the composition of the iron nail itself.

It's important to note that the attraction between the magnet and the iron nail is temporary. Once the magnet is removed, the magnetic domains in the iron nail gradually return to their random orientation, and the nail loses its magnetism.

In summary, non-magnetized iron nails are attracted to magnets because the magnetic field of the magnet aligns the magnetic domains in the iron nail, creating a temporary magnet and causing the attraction.
