Ways To Empirically Identify a Magnet’s Polarity
Ways To Empirically Identify A Magnet’s Polarity No comments by: Donald Papp September 27, 2026 Title: Copy Short Link: Copy Every magnet has a north and a south pole, but which is which? If a product one builds features a magnetic closure or other part, the polarity of those magnets should be consistent in assembly. So how does one ensure they never glue a magnet wrong again? [Clough42] shows several ways to identify a magnet’s north and south poles using things many of us probably have ready at hand, and goes into a bit of theory while he’s at it.

Ways To Empirically Identify A Magnet’s Polarity No comments by: Donald Papp September 27, 2026 Title: Copy Short Link: Copy Every magnet has a north and a south pole, but which is which? Sometimes it matters. If a product one builds features a magnetic closure or other part, the polarity of those magnets should be consistent in assembly. So how does one ensure they never glue a magnet wrong again? [Clough42] shows several ways to identify a magnet’s north and south poles using things many of us probably have ready at hand, and goes into a bit of theory while he’s at it. Probably the easiest way is to use a known-good and clearly labeled reference magnet. Same poles repel, and opposites attract. But if that’s not available, a simple magnetic compass can help.
