Electromagnetic levitation Relations

[wubbzee]

Hello everyone i bought a kit for my senior project on electromagnetic levitation. It uses an electromagnet to suspend a magnet via force of attraction. It is stable because of two hall effect sensors and voltage regulator. The kit can make the magnet move in a sinusoidal and tangential motion

If i want to study this and get a relation linearly what can i do? Whats something i can do with this kit to take measurements and process data?

I've thought maybe if i change the weight of the object suspended the gap between the electromagnet and the object itself would change? But maybe that's not true because the hall effect sensor would keep it in equilibrium?

Anyways this is NOT an ad but i bought the kit from here if you need more information zeltom.com

and i can basically study an aspect of this the strength of the magnetic felid, the gap of levitation, the current supply change... anything i just need your help!

Perhaps you could measure the current used by the circuit as you use different weighted magnets or change other conditions with the pushbutton controls.

yeah i think hooking up an ammeter is my best bet thanks for that! Would you have any idea what equations i would use?
I have general magnetic field strength and electromagnet equations... if you have anything else that'd also be appreciated.

Can you give a link to the kit?
