Some examples of permanent magnets are neodymium magnets, samarium-cobalt magnets, and alnico magnets. These magnets are made from materials that retain their magnetic properties for long periods without needing an external magnetic field to remain magnetized.
No, paperclips are not permanent magnets. They can temporarily exhibit magnetic properties when in the presence of a magnetic field, but they do not retain magnetism like permanent magnets do.
Permanent magnets are made from materials that retain their magnetic properties for a long time without the need for an external magnetic field. Examples include neodymium magnets and samarium-cobalt magnets. These materials have high coercivity, which allows them to maintain their magnetism over long periods.
Electromagnets and permanent magnets differ in how they are created and their magnetic properties. Electromagnets are temporary magnets created by passing an electric current through a coil of wire, while permanent magnets are naturally occurring magnets with a fixed magnetic field. Electromagnets can be turned on and off by controlling the electric current, while permanent magnets always have a magnetic field.
Permanent magnets can be found in stores that sell hardware or industrial supplies, as well as online retailers. Specialized magnet stores or suppliers may also carry a wide variety of permanent magnets for different uses.

not really. is depends on what kind of magnets they are.
Natural magnets, such as lodestones, have a permanent and persistence magnetic field. These permanent magnets can also temporarily magnetize material such as iron, nickel, and cobalt.
The three classifications of magnets are permanent magnets, temporary magnets, and electromagnets. Permanent magnets retain their magnetic properties over time, temporary magnets are only magnetic when in the presence of a magnetic field, and electromagnets are magnets created by a current flowing through a coil of wire.
