Magnetic Levitating Globes

By:   |   Jul 08, 2018   |   Views: 10   |   Comments: 0

The Levitating World Globes The assortment of Globes is made by Fascinations, inc.

I purchased this wonderful electromagnetic levitation device online at www.giftsunusual.biz. With Design In Mind could not be found at their warranty card address. I could not locate Pacific Levitation Systems Inc., either. Both may be out of business.

I opened the bottom cover plate to see inside this awesome science toy. I could not see everything as I would have had to destroy it to get it apart.

How I think it works !!!

The 8 inch world globe contains a large magnet inside the top and a small magnet inside the bottom. The top of the stand contains a large iron core electromagnet. The bottom of the stand contains a Hall effect magnetic field strength sensor. This senses the position of the globe by sensing the field strength from the small magnet in the bottom of the globe. The sensor provides input to the feedback circuit which controls the current provided to the electromagnet in the top of the stand. This feedback control circuit holds the globe in mid air. It provides rock stable levitation.
