Discuss the relationship between electric and magnetic fields.

What role does voltage play in the formation or use of an electromagnet?

If you were able to keep the electromagnet that you created in your laboratory activity, what would be two possible uses for the electromagnet rather than a regular magnet?

This is more of a physics question.
But the relatonship is that a magnetic field will be perpendicular to the electric field and vice versa. The relationship that exists between an electric field and a magnetic field is one of electromagnetic interaction as a consequence of associating elementary particles. 
The electrostatic force between charged particles is an example of this relationship. There are formulas which exhibit this also, but I don't know them. Im sure you can search for formula of electric field and magnetic firleds.

An electric field that changes with time (such as due to the motion of charged particles in the field) will also influence the magnetic field of that region of space. Thus, in general, the electric and magnetic fields are not completely separate phenomena; what one observer perceives as an electric field, another observer in a different frame of reference perceives as a mixture of electric and magnetic fields. ... In physics, an electric field is a property that describes the space that surrounds electrically charged particles or that which is in the presence of a time-varying magnetic field. A magnetic field is a field of force produced by a magnetic object or particle, or by a changing electrical field and is detected by the force it exerts on other magnetic materials and moving electric charges. The magnetic field at any given point is specified by both a direction and a magnitude (or strength); as such it is a vector field. for more: http://en.wikipedia.org/wiki/Electric_fi … http://en.wikipedia.org/wiki/Magnetic_fi …

A regular magnet, "Earth Magnet", can be very strong, the disadvantage of using them is that you cannot turn off the magnet. Electromagnet uses the electricity of a common battery and can be turned on and off, such as for switches in a circuit board.
