The product is already made finished product, including: host, levitation strong magnet, usb power cable (need to bring their own 5v phone charger).

Description：
1, magnetic suspension principle: in fact, all magnetic levitation principle is the same, Hall components sense the location of the magnet, adjust the size of the electromagnetic coil magnetic force to make strong magnet levitation.

This system coil core on the strong magnet gravitational force (F1) up, the coil energized magnetic field on the strong magnet gravitational force (F2) up, the strong magnet own gravity (G) down. When F1+F2=G, the strong magnet levitates successfully. For the small jitter of the strong magnet, the system will change the magnitude of the current into the coil to change the gravitational force (F2) of the magnetic field of the coil on the strong magnet, so that the system will continue to be stable. Because this product is made with streamlined circuit, the effective range where the strong magnet can be successfully levitated is very small (about 1cm below the coil).

2, product specifications: manual measurement, about 3.3cm long, 3.3cm wide, 3.8cm high, weighing about: 30 grams. Very small is suitable for the palm of the hand to play small toys. Mini magnetic levitation system is only used as a levitation demonstration, there is not much weight-carrying force, only 5-10 grams. Only the effect of the following picture levitating magnets, please know the buyer.

3, the indicator color random, you receive the product indicator color may be different from the picture below, because the light-emitting diodes are mixed together, all products may be: red, green, blue or will change color, please do not mind.

4, before energizing the host should be placed flat and fixed, keep the coil vertical (very important), levitate with a strong magnet in hand (do not shake, very important) N pole facing up near the coil. Slowly released at about 1cm below the coil. In general, the owner will be marked with a marker at the N pole of the magnet, look for this marker (N pole) when you receive the goods, so that it can be up. The suspension process requires buyers to have some patience, do not be impatient, remember the essentials slowly.

5, product debugging: the product has been debugged before delivery. If the test found not stable enough can also be adjusted by themselves, fine-tuning adjustable resistors. General is to adjust a trial, please do not adjust the adjustable resistor substantially, so as not to adjust the chaos.

In particular, buyers who bought more than two products, mixed magnets or suspended other small objects.

All need to re-adjust the adjustable resistance to achieve the best results. Clockwise, reduce the magnetic force of the coil, the magnet will drop some, if a strong magnet is always sucked up, you can properly clockwise fine tuning adjustable resistance.

Conversely, counterclockwise, enhance the coil magnetic force, the magnet will rise some, if the magnet always fall down, then you can properly counterclockwise fine-tune the adjustable resistance.

(Note: even if the host is not energized, if the magnet is too close to the coil, the magnet will be sucked up by the coil core, so you can not once the levitation is not successful to adjust the adjustable resistor. Only in repeated unsuccessful attempts to feel the need to adjust the adjustable resistor)
