Keep the magnetic properties of magnets

Explanation:
permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. An everyday example is a refrigerator magnet used to hold notes on a refrigerator door. Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include the elements iron, nickel and cobalt and their alloys, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone. Although ferromagnetic (and ferrimagnetic) materials are the only ones attracted to a magnet strongly enough to be commonly considered magnetic, all other substances respond weakly to a magnetic field, by one of several other types of magnetism.
Explanation:
Generally speaking, magnets below 3000 Gauss (magnetic field unit) are basically harmless to the human body, while magnets with magnetic field strength above 3000 Gauss are harmful to the human body. Some people are afraid that the magnetic field of the magnet will affect their health.
