Iron
No. A magnet is a material that produces a magnetic field. The MF is invisible and is responsible for the magnet's force that pulls on ferromagnetic materials such as iron. It attracts or repels other metals.
False permanent magnets can but electromagnets need a running current A+
Iron (or, from a physics standpoint, ferrous or, more probably, ferromagnetic metal). Magnets attract magnetic material, and there are only a few ferrous materials around. The word ferrous is from the word ferrum, which is the Latin word for iron. The chemical symbol for iron is Fe and it comes from the same source. Iron, cobalt and nickel are the "big three" ferromagnetic materials, but gadolinium and dysprosium also exhibit ferromagnetic properties. Certainly compounds and mixtures that include these elements are (usually) ferromagnetic. Wikipedia has some good info posted in their article on ferromagnetism. Need a link? You got it.

Yes, steel is a ferromagnetic material.
No, copper is not a ferromagnetic material.
No, lead is not a ferromagnetic material.
Yes, a magnet can repel a ferromagnetic material if the poles of the magnet and the material are aligned in a way that causes repulsion.
ferromagnetic material
A ferromagnetic material has a high magnetic permeability and can retain a strong magnetic field once magnetized. It exhibits spontaneous magnetization and can be easily magnetized and demagnetized. Ferromagnetic materials include iron, nickel, and cobalt.
