You need the correct size of magnets to hold on the part you are magnetising. A 3mm x 2mm magnet pack will happily hold on a crushing claw / scything talon. That size will also do pretty much any turrets/sponsons on tanks. For things like heldrake wings you want something bigger or to use pegs.
You should put them where they won't show. For example
http://www.youtube.com/watch?v=bFflA3Sgbik shows you how to go crazy with magnets. Personally I would only put in the ones you can see for the arms and stop there (that's what I have done). As long as the magnets are placed in the ball joints and are drilled in to be flush with the model they will only show when you remove the arms completely.
Magnetising hive tyrant/carnifexes is a must!
