When all of the magnet domains line up on their own, the material is called ferromagnetic. This alignment results in a strong magnetic field that can be observed in materials like iron, nickel, and cobalt.

If a strong magnet passed by an object with randomly arranged magnetic domains, the magnetic domains in the object would align with the magnetic field of the magnet. This alignment would result in the object becoming temporarily magnetized in the direction of the magnet's field until the influence of the external magnet is removed.
Iron can become a magnet when its magnetic domains align in the same direction. This can happen when iron is placed in a magnetic field, causing its domains to line up and create a magnetic field of its own. Once aligned, the iron will remain magnetized even after the external magnetic field is removed.
A piece of iron doesn't behave as a magnet on its own because the magnetic domains within the iron are not aligned to create a magnetic field. In order for the iron to become magnetized and exhibit magnetic properties, an external magnetic field must be applied to align the domains.

This is called 'bad grammar'.

Domains in a magnet are regions where magnetic moments of atoms or molecules are aligned in the same direction. These domains help maintain the overall magnetic properties of the magnet by ensuring a collective alignment of magnetic moments within each domain. When a magnet is magnetized, these domains align in the same direction to create a strong magnetic field.
Magnetic domains are tiny regions within materials where atoms align their magnetic fields in the same direction. When these domains line up, the material exhibits magnetic properties.
Permanent magnets are magnetic because of things called "domains." Domains are like mini-magnets in the large magnet - when they all line up perfectly, you get a noticeable magnetic field. When they don't, the domains cancel each other out, and hence, do not create a magnet. To demagnetize a permanent magnet, the domains must come out of alignment - this is most easily accomplished by imparting a large force to the magnet (hitting it with a hammer) Alternatively, electromagnets are created via moving charges in a coil of wire (electric current). These magnets are designed to be turned on and off, so demagnetizing an electromagnet is as simple as switching off the current.
Without magnetic domains a magnet wouldn't have its magnetism. Magnetic domains are clusters of iron atoms that line up in the smae direction when magnetised. When unmagnitized the iron atoms scatter.
When a strong south pole of a magnet approaches an iron nail, the domains in the nail will align with the magnetic field of the magnet. The domains will rearrange themselves in such a way that the nail becomes temporarily magnetized and attracted to the south pole.
