E&M, electricity and magnetism are very intertwined. A magnet is nothing more than an element with a bunch of the atomic level electric fields lined up, instead of randomly laid down.

A constant electric field will attract electrically charged particles, but not magnetic particles. A changing electric field will create a magnetic field and attract magnetic particles. So basically, run a current in a wire and you will get both electric and magnetic fields. Wrap the (insulated) wire around an iron or steel rod in the same rotation and you'll create a combined stronger magnetic field.

Here is a very low level run at E&M

I am a Mechanical and Electrical Power Engineer, but not an "Electrical Engineer". I know enough to be dangerous...
