Re: Tetrapolar magnet

I'm sorry! I didn't realize that the Quadrapolar and Tetrapolar 
magnets were one in the same... it's like learning another language 
sometimes!!!

Thanks for clearing that up for me, I felt silly asking such a basic 
question but if I don't get these things clear now, I'm sure it 
won't do me any favours in the future :-)
