Yes, as your aura becomes stronger, and radiates further from the body as a result, it does start to influence others and bring about that quality of personal magnetism.
And, yes, you find that people just start liking you for no obvious reason.
There are also other benefits to having a powerful aura such as the ability to heal others with your hands.
This is because the fingertips (the first three of each hand) are "outlets" for excess aura energy which can be used to "charge" others who may feel depleted.
There is also one other significant overflow outlet for a powerful aura. That is on the left side of the head and it can eventually form a complete ring.
Those who are sensitive to seeing auras can, in those highly-developed people, see that ring around the head...now you know what a halo really is :)
