The magnets I bought included a very small divot, marking the North-Seeking Pole. Isn't the North-Seeking Pole, Negative & the side that sticks to the refrigerator all the same spot?
I found magnets 4" x 1" (x 1.75" deep) 100# pulling power. Four of these would create a space 4" Tall with 1" sides minimum - just about perfect to slide in a 2 oz bottle. I am assuming that the space created should have an incredible magnetic field.
Is a 4 sided magnetic field overkill, am I way off base?
