As is well known, magnets are things that can adsorb iron substances, such as iron nails, iron keys, iron filings, etc. So besides these objects that are clearly composed of iron, what other objects can be attracted by iron?

So first, we need to analyze the composition of the magnet. The components of the magnet are atoms such as iron, cobalt, nickel, etc. The internal structure of its atoms is relatively special, and it itself has a magnetic moment.

So magnets can generate a magnetic field, but only a small portion of metals can be attracted by magnets, such as iron, nickel, cobalt, and other magnetic loving metals.

Most other metals are not attracted, such as gold, silver, copper, aluminum, tin, lead, titanium, and so on.

Of course, in addition to attracting metals, there are also some objects that exhibit diamagnetism and paramagnetism.

Demagnetism: Demagnetism is a magnetic phenomenon that occurs when a substance is subjected to an external magnetic field, resulting in a weak repulsive force on the magnetic field.

Paramagnetism: Paramagnetism refers to the magnetic state of a material. Some materials can be affected by an external magnetic field, resulting in the characteristic of having magnetization vectors pointing in the same direction. Such substances have a positive magnetic susceptibility. The phenomenon opposite to paramagnetism is called diamagnetism.

Ferromagnetism: Ferromagnetism refers to the magnetic state of a material with spontaneous magnetization phenomenon.
