On the basis of electromagnetic attraction
see how powerful and effective the dynamic is
between the different types of polarity.
The higher the number, the greater the compatibility*
*This does NOT mean they will not be attracted to one another. Couplings at the lower ends of the scales are often attracted to one another as they recognise themselves in the mirror and enjoy the comfort it brings. It’s just that they are then stuck in a rut. The exception to the rule is ‘0’ where with 0+ it’s like trying to push two magnets with positive polarity together – they just push each other apart; whilst with ‘0-‘ there is no magnetism at all and like two minus polarity magnets they just rub off each other.
