I haven't ever directly taken raw magnets on an airplane, but I have flown a with small combat robots (150g-3# divisions) and may have some advice to anyone trying to bring robot parts on an airplane.

The best thing you can do is disconnect all the wires you can. The FTA ussualy gets unhappy. One time, they unpluged my battery charger from its power source even though neither were plugged into anything. Then procced to tie both ends of the wires in a knot, that wasn't fun.

Next: provide a small letter for the person that will check your bag. Include what you are doing, the organization name, and what the bot is supposed to do. Include a full list of all the robot parts in the bag. I have recieved a "cool!" on these letters before, and a "congradulations!" on the back of the note they like to put in your bag to let you know they checked it.

Hope this will help some teams, and sorry I don't have anything specifically about high powered magnets.
