Title: Which magnet has the strongest magnetic field at its North pole?
Post by: ciniva on 27/10/2017 10:27:21
Which of the magnets in the image below has the strongest magnetic attraction on the North pole (in order).
I think the order follows (B, C, D, A)
With magnet 'A' the thickness exceeds the diameter dimension (thickness may weaken its magnetic force on the poles)?

Am I right?
