In Human Design, we call this an “electromagnetic connection” because it is seen as an interaction where there is a magnetism. It can feel like a rush of energy in an otherwise quiet part of your being. The more of these connections there are in a relationship, the more intense the chemistry. What I would say is that no relationship would want too many of these connections, though, because they can cause an overload of electricity leading to blowouts that are not conducive to long-term love.
