12 October 2018 Question by: Mario | Product code: 67-1120
Q. Where is the south and north poles on these magnets?
A. Hi Mario, thank you for your question. This is not marked on the magnet so it would be either one side or the other. It can be identified as follows: "Take a compass and bring it close to the Neodymium magnet you want to mark. The North Pole of the compass will be attracted to the South Pole of the Neodymium magnet and repelled by the North Pole."
