Flying Saucer

Furthest exactitude technological toy
With magnetic induction

Needn't electric
Without fulcrum
Suspend of sky

Elements analyse

Refer physics episteme and concept

Law of inertia, conservation of energy, earth magnetic field, elements peg top spindle, and so on.

Power analyse

For law of inertia: When flying saucer suspending, composition of forces for zero, expressions:G+F=0. G is gravitation bearing uprightness adown; F is repulsion of magnetic field.

Operation analyse

Magnitude of power: repulsion of magnetic field F is fixed value, for weight adjuster, make G+G1+G2=F (G1 is flying saucer, G2 is weight adjuster) Power bearing: make F and G in a beeline.

Operation

Suspend flying saucer demo the physics electrophoresis of suspend.

Choose the concourse

Anywhere is jarless and apart from somebody is feedback of magnetism

Circumgyrate

The flying saucer circumgyrate must make it jarless.

Means of circumgyrate

Tweak the axostyle of flying saucer, keep it on the centre if splint, the flying saucer reatin level, add a little Drang, circumgyrate speedy of power.

Adjust the weight of flying saucer

Use the weight adjuster of to adjust the weight of flying saucer. Keep G = F, you can adjuster the weight more than 0.1-8g, adjust the weight more exactitude, it will more level off and keep longer time.

Means ameliorate

Too light: Drive up the splint slow, the flying saucer will fly out, add 1-6g copper weight adjuster.
A little light: When the flying saucer suspend the splint it cicumgyrate is not jarless, add 0.1-2 weight adjuster.
Too weightily: The flying saucer can not fly off the splint, lighten the copper weight adjuster.
A little weightily: The flying saucer suspend a few time then drop, lighten the plastic weight adjuster.

Adjust batholith angle

Use angle adjuster adjust magnetic field angle, make the batholith in right fettle.

Suspend course and operation

First keep the splint onto the batholith, circumgyrate the flying saucer in the center, put up the splint slowly 3-4cm, the flying saucer will fly off the splint, then the game is succeed.

With differ time and place

Although the flying saucer is adjusted, with differ time and place, it will feel too light of too weightily. It must be adjust again.

Think and mentality

Testing balance ability: Search magnetic field centre and circumgyrate. Test out the take pains and the backbone: adjust the magnetic field balance and the flying saucer weight. Check out the manipulate: More steady and more celerity circumgyrate the flying saucer, then make it suspend.
