Best Answer

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.

What is true of permanent magnets?

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.

Are permanent magnets only attracted to other permanent magnets?

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.
