Permanent magnets have their own magnetic field that does not require external electrical current to maintain. They can attract or repel other magnetic materials without losing their magnetic properties. Common materials used for permanent magnets include iron, nickel, and cobalt.
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 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.
No, permanent magnets can also be attracted to ferromagnetic materials such as iron, cobalt, and nickel. This attraction is due to the alignment of magnetic domains within the materials, resulting in an attractive force between the permanent magnet and the ferromagnetic material.
Some examples of permanent magnets include neodymium magnets, samarium cobalt magnets, and ceramic (ferrite) magnets. These magnets retain their magnetism without the need for an external magnetic field.
A permanent magnet retains its magnetism without an external magnetic field, whereas a non-permanent magnet only exhibits magnetism when subjected to an external magnetic field. Permanent magnets are typically made of materials like iron, nickel, and cobalt, while non-permanent magnets are usually made of materials like soft iron or steel.
They are difficult to magnetize,

They only point to the Magnetic NorthA compass is a permanent magnentA compass is a permanent magnet. A compass has both a south pole and a north pole. Compass magnets can be deflected by Earth's magnetic field or other permanent magnets.
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.
No, electromagnets are not permanent.
Permanent magnets retain their magnetism without the need for an external magnetic field. They are typically made of materials such as iron, cobalt, and nickel, and have north and south poles that attract or repel each other. Their strength and duration of magnetism depend on factors like material composition and manufacturing process.

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.
No, permanent magnets can also be attracted to ferromagnetic materials such as iron, cobalt, and nickel. This attraction is due to the alignment of magnetic domains within the materials, resulting in an attractive force between the permanent magnet and the ferromagnetic material.
