Magnet Strength: North vs South Pole

Click For Summary
SUMMARY

The discussion centers on the magnetic strength of a conical magnet, specifically comparing the north pole at the apex and the south pole at the base. It concludes that the density of magnetic field lines, or magnetic flux, is likely greater at the apex due to the concentration of lines emanating from the poles. However, the alignment of magnetic domains within the cone suggests that more flux lines may emerge from the sides, potentially reducing the flux density at the apex compared to the base. This creates a complex interplay between the shape of the magnet and the distribution of magnetic strength.

with an odd shaped magnet eg a cone .. apex = N / base = S

is the strength of the magnet the same at each pole ?
 
Physics news on Phys.org
Consider the density of magnetic field lines (magnetic flux), assuming the opposite poles are at apex and base, that the lines are conserved and that the majority emanate from the poles.
 
Forgive my ignorance .. I'm FAR from being a physicist ..

"that the majority emanate from the poles" .. this would imply the flux density would be greater at the apex then the base ..

if one envisions a parrallel alignment of magnetic domains within the conical shape .. it would seem reasonable to assume more flux lines emininate from the "sides". If this were the case the flux density would be less at the apex then the base ..
