Product introduction:

An intermediate cone-shaped concave round table， a rotating gyroscopehas been running up and down， for a long time not see it stop...... This is"to stop the electromagnetic gyro. Product color with elegant piano black，texture delicate.

You can do science education training / Kindergarten / primary schoolsecond class / science education technology interest group playing AIDS，but also can be used as parent-child new small gifts， science contestprize， products are easy to use， miraculous phenomenon， to experiencethe charm of science， Ji Faxing!

Can also be used as a social science activities， science and technology festival experience exhibition. Even as a junior high school， high school，and university physics can be deep or shallow teaching aids， worthy of our reference qualitative or quantitative analysis in teaching.

Thinking is the greatest joy of Galileo

Scientific principle:

The appearance is a conical central low， high edge， spinning gyroscopeis a coated with a layer of plastic magnets. When the gyro rotation，magnetic gyro by cone rim toward the center of rotation， the coil turntableunderneath， so according to Lenz's law of coil induced current， when thecurrent reaches a certain value， triode， iron core in a coil formed a temporary magnetic iron core， which formed at the upper end of the pole，on the top part of magnetic pole 'Yi'an culture right hand rule that'， the formation of same-sex repulsion phenomenon， the rotating magnet gyrois pushed， speed.

In fact， a conical table top edge of the rotating cone central to lower，because the potential energy is converted into kinetic energy， so thegyro rotation speed can be accelerated， priming induced current， and thespinning cone on a push， speed changes quickly， and then by the lowergyro rotary cone the central Taiwan in inertial and rotating to a highconical edge， speed and therefore slow (kinetic energy into potential energy， but also by the friction loss of a part of the kinetic energy).

Gyro from the turntable to the highest point of the cone bottom， go round and begin again returned to the highest point phenomenon does not stop， the secret is to stop gyroscope.

Use: ★ ☆ ☆ ☆ ☆ difficulty using a simple， novel， advanced phenomenonprinciple

Object: the use of kindergarten， primary school， middle school， high school， University

Method of use: open the bottom cover， the battery (products carried) andpositive and negative joint buckle， alloy on the cover， then the gyro in therotary cover turning， you will see the gyro long time non-stop turn down
