How is the ball bearing method secure when all the thief needs is a magnet? Have I missed something here..
Typically it's ball bearing + glue, wax or something else fiddly to remove. Nothing's going to make anything unstealable - it's all about making risk vs reward for the thief not favour your bike over anyone else's.
