Auroras (North or South Polar Lights) are natural colored light displays in the sky, usually observed at night, particularly in the polar zone.
Scientists have now discovered that auroras are caused by variations in the Earth’s magnetic field resulting in the collision of charged particles in the atmosphere. To learn more go here or here.
If you are struggling to understand magnetism the Wikipedia page might be a bit complex. So you could try the Simple English Wikipedia site. If it is still a bit confusing maybe this poem will help:
I wish I could’ve turned athletic,
But just my luck… I’ve turned magnetic.
Paper clips fly up to greet me.
Nails, it seems, can’t wait to meet me.
I’m sticking to the baby’s stroller.
Look at me, I’m so bi-polar.
I make the TV super active.
At least the spoons find me attractive.
The phone’s for me? What’s that you say?
Why don’t I come out to play?
I think I’ll have to join you later…
I’m stuck on our refrigerator.
