[sigma 1 (OP)]

I’ve got a foreverspin spinning top, and it does spin a long time. What I’ve found is that on a flat surface, when I spin it going clockwise, it always wanders south. Counter clockwise it wanders north, every time. So, may be something everyone knows, that yeah, that’s just how it works. But couldn’t find an explanation based on searches, so thought I’d toss it out here. So, is it earth's magnetic influence, earth's spin, possessed top?

Hi @sigma 1
🙂

Hmm...spinning top changing directions.
But directions always remain constant.
Hence, it's my guess that it must be dragging & pulling itself on the floor...just like an automobile rubber tyre rotating horizontally...makes sense?
(That's how a NewBee answers)

Now...You want a SmartyPants explanation...then here it goes...
" A rapidly spinning top will precess in a direction determined by the torque exerted by its weight. The precession angular velocity is inversely proportional to the spin angular velocity, so that the precession is faster and more pronounced as the top slows down. "

Lol...yeaah, i know!

P.S. - A top that spins for a very veerrry loooong time Cannot be defined as a Forever spinning top.
👍
(But what if You spun it in deep space???)
