For example, if a positive charge and a negative charge all of the sudden come into existence at the exact same time, would there be a delay before the force between them occurs? This would happen if the electric field travelled out of the positive charge at a finite speed because it would take a certain amount of time for the negative charge to recieve it and be influenced by it.

I was told that these propogate at the speed of light in vacuum, but that was in physics classes in college some 13 years ago.

Nothing is travelling, it is just a magnetic force field. Where electricity is involved you are talking about electromagnetic force fields. Ferrous metals like iron have miniature magnets in their interior, by stroking theses materials with a magnetized object you will cause these miniature magnets to line up, the more they line up the more powerful will be the magnet.

Disruptions in the electric field travel at the speed of light.

Nothing travels faster than speed of light. Including information.

no ,it can not travel at a finite speed because it vary.the intensity of field vary with distance.
by formula
E is proportional to 1/distance square.

If the charges were 1cm apart it would take one thirty-billionths of a second before they were aware of each other.
Nothing is instantaneous.
