P-90 Magnet Direction

A friend of mine has a P-90 equipped Les Paul and the pickups are out of phase. I know I could flip either magnet, but I'd like to flip the correct one. Can someone tell me, if I'm looking down at the top of the pickup and the lead is on the right (again, looking down at the pickup) should the north pole of the magnet be on the top or bottom?

Never mind. Found out and flipped them.
