Answer: A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets.
If two metal, say iron , attract each other it shows a magnetic pull. Also metal can attract other metal only if it has magnetic fields. Remember to note that the metal should attract Ferromagnetic materials only.
