Specific embodiment
A kind of coil that can be danced and aluminium ring, it is characterized in that including instrument base (1), instrument base (1) above jump by device branch
The coil of dance and the aluminium ring two parts that can be danced；The coil that can be danced stresses to disclose the principle that electrical conductor moves in magnetic field,
It is connected to coil power binding post (12) including 12v transformer (9) 12v transformer (9), coil power binding post (12) elasticity
Coil power lead-in (13) connects coil (10), is installed with jump on device permanent magnet (11) circuit below connection coil (10)
It waves coil power button (3)；The aluminium ring part that can be danced stresses to disclose the principle that alternating magnetic field cutting conductor generates induced current,
Including jumping ring coil (4) and inserting in iron core column therein (8), aluminium ring (7) are cased in iron core column (8)；Device jumps loop wire in circuit
It encloses power knob (5)；For the interest for increasing demonstration, patent device remote control circuit, including remote control signal receiver (6) are distant
Control device (15) and remote manual control change-over switch (14).
Examination on experimental operation and its principle
Aluminium ring two parts that the experiment of the invention patent is divided into the coil that can be danced and can dance:
1, the coil that can be danced: powering on from outlet (2), presses dancing coil power button (3), coil (10) will
It jumps up, if long-pressing power knob (3) coil (10) will dance always on permanent magnet (11).
The principles of science: there are magnetic field around electrical conductor, coil will generate magnetic field after being powered, the magnetic with the permanent magnet of lower section
Field interactions, coil will generate movement；When length touches the button, due to using alternating current, the current direction in coil is
Do not stop transformation, therefore alternating magnetic field can be generated, and the magnetic field of permanent magnet is constant so coil will be on the permanent magnet
Ceaselessly dance.
2, the aluminium ring that can be danced: powering on from outlet (2), presses and jumps ring coil power knob (5), aluminium ring will be upward
It takeoffs, release button (5) aluminium ring falls cling-clang, clicks, and aluminium ring (7) will jump up, if long-pressing is not put, aluminium
Ring (7)
It will suspend in the sky.
The principles of science: due to using alternating current, when pressing jump ring coil power knob (5), the alternation in ring coil (4) is jumped
Electric current makes coil generate alternating magnetic field, and the principle of induced current can be generated according to conductor cutting magnetic line, due to jumping ring coil (4)
Alternating magnetic field cut aluminium ring, alternating current will be generated in aluminium ring, according to the principle around electrical conductor there are magnetic field, aluminium
Alternating current in ring can make aluminium ring generate alternating magnetic field, interact with the alternating magnetic field for jumping ring coil, so that aluminium ring be made to produce
Raw movement.
3, manual and remote control operation: in order to keep experiment more interesting, the invention patent devises manual, two kinds of operation sides of remote control
Method, when experiment, press remote manual control change-over switch (14) and can realize manually and the interconversion of two kinds of operating methods of remote control.
