If I have 2 dissimilar magnets and push their North (or South) poles towards each other, how do I calculate how much force they will repel with. Again, I'm asking for calculations since I'd like to know before I buy magnets. I'm guessing they are either additive or they only push with a force...

This is what I was thinking was happening. Which leads me to another question, if that is the case: can I make an electromagnet with a non -ferrous core and still have a defined magnetic field shape and still some strength to it?

I wired a quick weak electromagnet. How come when I put a small permanent magnet close to it, both sides of the permanent magnet (north and south) are attracted to the same side of the electromagnet?
