Is it true, that, what ever side of a coil the current comes out of first THAT will be the positive terminal?

From Jacaranda: The terminal from which the current emerges at a particular instant is acting as the positive terminal

This knowledge works for questions I've tried, but It's not something I particularly understand - doesn't current flow from positive>negative (well Conventional)? So why should it becoming out of the positive terminal?

As you just said, conventional current comes from the positive terminal (goes from positive to negative). Sorry I don't see what's not to understand.

Well the current would be emerging from a positive terminal, but shouldn't it be emerging from the negative terminal in conventional current? (Goes from positive>emerges at negative terminal)

Electrons from negative terminal, conventional current from positive?

I think I am missing the context of what you are asking.

With an induced EMF, you are increasing charges potential. It is like pushing water up hill. Once the induced EMF has increased the potential, it then flows down again.

So the induced EMF pushes the current to the positive terminal, it then flows if an external circuit is present from positive to negative.

I just got it, should have read the thread title.
