Physics, Astronomy & Cosmology / Sudden polarity reversal in opposing permanent magnets?
« on: 22/05/2020 20:09:14 »
Hi all,
I'm working with a pair of multi-pole neodymium ring magnets (rated ~119lbF, McMaster-Carr part number 2494N17) and finding that if the opposing poles are forced together, with the magnets in alignment, that at very close range (may be a millimeter or two apart?) the two magnets will suddenly snap together as if one has reversed polarity. There is NO electric current involved, but the only resources I am finding about this phenomenom are related to electromagnets and induced magnetism.
Can anyone point me to a source explaining what's happening?
Thank you!
