3. Some people use the word "power" to describe magnetic field strength, when they really should be speaking in terms of Teslas or Gauss, not Watts.
4. Some of the rest of us were making our best attempt to guess what might have been the actual meaning of the question, given that it might have been formulated or relayed in an ambiguous manner.
5. The suggestions make sense. They might not be correct, but they were hardly nonsense. If I had suggested the OP purchase a box of magnetic monopoles, your assessment would perhaps be more justified.
1. Not enough information.
2. Lots of guesses based on a lack of information.
3. The suggestion to get a simple standard magnet makes sense (I didn't say otherwise).
4. The other stuff is weird speculative nonsense based on not enough information. None of which is likely relevant to the odometer mentioned.
