A magnetic field is a vector field in the neighbourhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable. ... Magnetic field and electric field are both interrelated to each other and are components of the electromagnetic force, one of the four fundamental forces of nature.
Ferromagnetic materials are those materials that are strongly magnetised and attracted when they are placed in the external magnetic field. Examples of ferromagnetic materials are iron, cobalt and nickel. - Note that once the external magnetic field is removed, the paramagnetic and diamagnetic materials demagnetise.
