Various types of Magnetic Field use materials, such as iron 

and small compasses

Standard 5.0physics

 Electro magnetic:relating to the interrelation of electric currents or fields and magnetic fields

magnetic field:a region around a magnetic material or a moving electric charge within which the force of magnetism acts.

magnet:a piece of iron (or an ore, alloy, or other material) that has its component atoms so ordered that the material exhibits properties of magnetism, such as attracting other iron-containing objects or aligning itself in an external magnetic field

iron fillings:Iron filings are very small pieces of iron that look like a light powder. They are very often used in science demonstrations to show the direction of a magnetic field. Since iron is a ferromagnetic material, a magnetic field induces each particle to become a tiny bar magnet.

electrical currents:An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in a plasma

  ?1how can you prove your theory correct

?3how strong can the magnet be

.the magnet would not be able to attack anything

.the magnet would be not as strong
