If Earth's magnetic poles are strong enough to attract needles all over the world, why aren't they dangerous?

Question

Dangerously strong?

Like you toss a coin while standing on top of a magnetic pole and when you try to catch it, it would bring your hand to the ground, so strong the magnetic force is.

I'm thinking in comparison of those huge magnets that can squish your head so strong they are.

Answer 1

Electricity is in the nature of us all. Every single thing whether it is a living thing or an object, produces its own magnetic field because of the flow of electrons inside our bodies. That's what we call an Electric current. The electric current creates a magnetic field around it and because it is a ...current, it has a direction.

The needle turns because its own magnetic field needs to be aligned to that of the earth. Opposites attract, remember? As long as there are tho opposite sides on an object, say... a needle, charged with some extra electrons (easily done by rubbing the needle on a jean) and as long as one side has more electrons than the other, we call the two sides "poles".

Yeah, but what makes the Earths magnetic poles? Not giant space jeans of-course! As the Earth rotates, the different layers of it's inner core rub with each other, because are in liquid state. So the Earths rotation creates the magnetic poles.

Why this force is not destructive? Because of it's power. It is powerful enough to keep us on the planet's surface, but not powerful enough to crash us!  We learned to tolerate it, we (and our world) developed after and because of it after all!

Answer 2

The magnetic field strength reduces with the square of the distance, and the source of earth's magnetism is deep below, in the core of the planet. So, everyone is about uniformly distant for the "magnet" (so, experiencing about the same field strength; which is not that powerful anyway, compass needles are light and are pivoting on low friction axis in order to work) but that distance is quite large.
