I'd rather have manually induced signals than a magnet, ideally something that could use low power bluetooth (or similar) to talk to my smartphone. Maybe a set of muscle-twitching electrodes to replace vibrate mode on my phone, or to poke me for anything else that I'd want to be notified of.
With enough outputs you even do things similar to the vibrating compass belt that's mentioned elsewhere in the comments. Or instead of a north-compass, it could point you toward any arbitrary destination via GPS.

Or just gloves instead of implants. So you can take them off, but still get the benefit when they're on.
I don't see why it isn't possible.
Definitely more what I had in mind
