tinman,
An electric or magnetic field are one and the same thing. We give them different names only because we sense and measure them using different ways. Any change in one seen will produce or be caused by a change in the other.
If you look at the electric field of a point charge from any angle you the same field (shape - all lines radiating from a central point until they reach another point charge of different value).
If you look at the magnetic field of a magnet from the polar perspective you will see the same as the above electric field.
'Magnetic field' is simply another name for an electric field with curl.
If you really wish to see the only example of a true magnetic monopole consider the magnetic field around a straight piece of wire carrying DC. There are no poles, only direction and spin that doesn't change unless the electric current changes direction.
This is a bit deep but explains some thoughts on the subject.
http://www.electrostatics.org/images/C4.pdfNorth & South poles of any magnet are only a human construct. They are only references devised by us so we could better explain what we saw.
Further more, I don't believe there is such thing as negative and positive charges. There are only variations of charge, none, low, high. The high charge always goes to the place where low charge exists. Or, higher energy always moves to the place where low energy is. Good luck finding any place or thing with absolutely zero charge. All charge is relative but there is no place or thing with absolutely no charge. Any positive charge is simply less charge than the negative charge associated with it.
Nature abhors imbalance.
So, if you had two magnetic monopoles they would try to join while having equal velocity and direction. ( A bit like gravity, isn't it
)
If they had a velocity and direction difference between them and they crossed paths, they would repel each other most energetically where their paths crossed but there would not be attraction.
If both were completely without velocity there would be no interaction between them, at all. Since this is impossible (everything is always moving with some relative velocity) we will never see them.
Everything I stated in the previous three sentences also describes point charges. Why? Because a point charge is a magnetic monopole.
Many of these constructs only created by us are also considered to be constants so, welcome if you get your feet wet on these subjects. It can be rough weather in here
All above are my opinions and the opinions of many others.
