Are iron, cobalt, and nickel magnetic substances?

Yes, iron, cobalt, and nickel are magnetic substances because they possess ferromagnetic properties. These metals can be magnetized and exhibit strong attraction to magnets due to their atomic structure. Ferromagnetic materials have electrons that align in the same direction, allowing them to generate a magnetic field. This property makes iron, cobalt, and nickel ideal for use in magnets, motors, and other magnetic applications. Their strong magnetic characteristics are utilized in a variety of fields, including electronics and industrial machinery.
