Even with that much attraction you'd be surprised, there are too many forces on an external magnet. Water puddle hit at speed can easily move or remove one, it instantly moves a car weighing much more than 50 lbs. Putting mag inside perfect, you don't NEED to pull it and clean it, just leave it alone. Moving an external magnet will not carry all the particles with it, some will stay behind to then be loose, a mistake. The oil itself has enough resistance to pull some of the particles loose off magnet. The crankshaft could care less about any magnet in there..........
