What metal is not attracted by magnets?

Magnets are not just magnets that attract iron. They can create a magnetic field and possess the properties of attracting ferromagnetic chemicals such as iron, nickel, cobalt, and other metals. Magnets often attract iron due to the actual effect of external magnetic fields, the micro magnetic fields of the iron itself will change along the direction of the magnetic induction line, resulting in a magnetic field that is consistent with the direction of the external magnetic induction line of the magnet. The entire process of metal material being sucked is the complete process of forcibly changing the rotation direction of internal electronic devices.
The components of a magnet are atoms such as iron, cobalt, and nickel, and the internal structure of the atoms is relatively unique, possessing magnetic moments themselves. So what metal is not attracted by magnets?
1. There are actually a few metals that can be attracted to magnets, limited to a few ferromagnetic metals such as iron, nickel, cobalt, or alloys containing these three metals. The vast majority of other metals such as gold, silver, copper, aluminum, tin, lead, titanium, etc. are not attracted to magnets.
2. A magnet is an object that can generate a magnetic field, which is a magnetic dipole that can attract ferromagnetic substances such as iron, nickel, cobalt, and other metals. The determination of magnetic poles is based on a thin wire hanging a magnet. The magnetic pole pointing north is referred to as the North Pole or N Pole, and the magnetic pole pointing south is referred to as the Guide Pole or S Pole. If we think of the Earth as a large magnet, the current magnetic north pole of the Earth is the N pole, and the magnetic south pole is the S pole. Magnets with different poles attract each other, while those with the same pole repel. The Guide Pole attracts the North Pole, repels the Guide Pole, and repels the North Pole.
