They don't start anywhere They're closed loops

Nah the point is, you can't define a starting and ending point for a closed loop. Circle ka starting point kisko patha hoga? You can define one arbitrarily, but that's your choice.

You could say, magnetic fields actually start from the middle of the magnet, go to North pole, then come to South pole. It's absolutely right.
