If by "unconscious" you mean asleep, not many.
If by "unconscious" you mean unaware, plenty. Try walking past these in a lab:

FYI: Neodymium magnet strength is of order 1T, same as MRI.
- AkThhhpppt 15y agoSee where I mentioned the implant "rolling over"? That was caused by someone waving a stack of over 20 of these type of neodyms (http://www.magnets2buy.com/acatalog/neodymium-discs.html http://www.magnets2buy.com/acatalog/neodymium-discs.html) within an inch of my finger. Those are so powerful that splitting a stack of 8 and letting them re-attract rejoins the stack with such force it smashes the magnets that make contact. So while I'm sure coming close to one of those would _hurt_, I don't think I'd either end up stuck to the magnet or having the implant dragged out of me. The implant is powerful for its size, but its size is _tiny_ (half a grain of rice is a good comparison). It's not going to be as strongly attracted as that.
