hen a wire carrying a current is wound into a series of loops called coils, each turn of the wire produces a magnetic field. The magnetic fields produced by these turns add together to produce a stronger magnetic field. A magnet formed in this way is called an electromagnet.
If you insert certain kinds of metal, such as iron, into the coil, the strength of the magnetic field increases even more. Iron contains tiny regions called domains that act like tiny magnets. Normally the domains point in all different directions. As a result, the iron metal is not magnetic. When an electric current passes through the coils, however, the domains line up. This adds to the strength of the electromagnet. The diagram shows a simple electromagnet with a wire coiled around a nail.
Think about another factor that might affect the strength of the magnetic field around an electromagnet. Express this as a question that you could answer through an investigation

Answer:

Hope it helped ↓

Explanation:

Electromagnets are basically coils of wire which behave like bar magnets with a distinct north and south pole when an electrical current passes through the coil. The static magnetic field produced by each individual coil loop is summed with its neighbor with the combined magnetic field concentrated like the single wire loop we looked at in the last tutorial in the center of the coil. The resultant static magnetic field with a north pole at one end and a south pole at the other is uniform and a lot more stronger in the center of the coil than around the exterior. So a good question could be "Are electromagnets a magnet that respells, or attracts?" Then find away to explain that question/

(you don't have to do this question it is just a example.)
