Abstract
The invention discloses a physical teaching aid capable of demonstrating magnetic levitation which can enable a magnet to suspend in the air. The physical teaching aid is composed of an L-shaped base frame and large and small ring magnets. The phenomenon that the magnet is suspended in the air can be demonstrated, composition and decomposition of white light can also be demonstrated, and the inertia potential energy for the earth counter clockwise rotation can also be explained.
Description
Technical field
The invention belongs to teaching aid technical field, specifically one can demonstrate maglev physical teaching aid.
Background technology
At present, teacher of physics is when explaining the physical properties of magnet, and majority is all take two blocks of magnet to demonstrate the Physics of Magnetism experiment of " magnetic of the same race is repelled mutually, and xenogenesis magnetic attracts mutually " as teaching aid; When explaining magnetic levitation, teacher can only explain abstract physical theory, does not also have so far to allow magnet be suspended in aerial physical teaching aid.
Summary of the invention
The technical problem to be solved in the present invention is, it is provided that a kind of can demonstrate magnetic levitation magnet can be allowed to be suspended in aerial physical teaching aid.
The technical scheme that the present invention takes is: can demonstrate maglev physical teaching aid, and it comprises " L " shape pony sill, size two pieces of circular ring magnets, it is characterized in that: at the big magnet of planar upper annular of the base of " L " shape mounting; On the cylindrical vertical frame top of " L " shape mounting, cover has up and down slidably gyro axis stock; Cylindrical vertical frame bottom cover have up and down slidably and rotating gyro axis point spacer; It is fixed with spacing cover at the middle part of cylindrical vertical frame, spacing puts the axle sleeve axial line that can make gyro axis stock and the depression steady brace concentric up and down with the axial line of the big magnet of the annular on base of gyro axis point spacer; The magnet gyro of the band axle that useful annular small magnet is made on the depression of gyro axis point spacer; Below annular small magnet, magnetic pole is identical with the magnetic pole above the big magnet of the annular on base; In the upper surface of this magnet gyro, have between red champac three form and aspect or between red, orange, yellow, green, indigo, azure, purple seven form and aspect in radiation shape and color block, magnet gyro axis has pinion(gear); Axle more than pinion(gear), is enclosed within the cover of gyro axis stock; Both sides outside the cover of gyro axis stock have the track for limiting the slip of plastics tooth bar stretched out respectively downwards; The plastics tooth bar back of the body can slide with track, and the little tooth of plastics tooth bar can engage with the pinion(gear) on magnet gyro axis.
Adopting this teaching aid that above technical scheme produces, when demonstrating, the first step, upwards slides into the gyro axis of cylindrical vertical frame bottom point spacer the steady brace internal locking of spacing cover, 2nd step, puts into magnet gyro point the depression of gyro point spacer, 3rd step, slides to the gyro axis stock on cylindrical vertical frame top downwards in the steady brace of spacing cover, makes the cover of gyro axis stock be enclosed within magnet gyro axis, 4th step, the right hand takes plastics tooth bar draw ring end upwards to fill in plastics tooth bar track, and the tooth of plastics tooth bar is engaged with the pinion(gear) on magnet gyro axis, 5th step, left hand pins the top of cylindrical vertical frame, and the right hand pulls out plastics tooth bar fast, and such magnet gyro just can rotate counterclockwise fast, 6th step, upwards slides the gyro axle sleeve in cylindrical vertical frame and locks, 7th step, the gyro of the cylindrical vertical frame bottom first slide downward of point spacer in rotation, moves out between the big magnet of annular and the axis of magnet gyro, at this moment just can see that magnet gyro is suspended in the top of the big magnet of annulus, and long-time suspension is rotated, can also see simultaneously between red champac three form and aspect on gyro upper surface or between red, orange, yellow, green, indigo, azure, purple seven form and aspect in radiation shape and color block, become the look block of a circular white, when plastics tooth bar is filled in the track of another side and is pulled, this magnet gyro just can rotate clockwise and be suspended in the top of the big magnet of annular by same rotating speed, but the time suspended is slightly shorter compared with rotating counterclockwise, this rotates counterclockwise due to the earth to drive the object on the earth equally also to rotate counterclockwise, and have certain potential energy rotating counterclockwise inertia, therefore when magnet gyro and earth rotation rotating in same direction, the time being suspended in aerial rotation is just long, when magnet gyro and earth rotation backwards rotation, the time being suspended in aerial rotation is just short, therefore also it is all like this in nature, under affecting without human factor, the fluid whirlpool of self-assembling formation, such as water whirlpool, the whirly of the land of spring and autumn, big typhoon on wind spout and sea all rotates counterclockwise, that is they are all cause rotate counterclockwise due to the potential energy of earth rotation inertia.
The invention has the beneficial effects as follows: magnetic levitation 1, can be demonstrated, magnet can be allowed to be suspended in aerial physical teaching aid; 2, the decomposition and synthesis of white light can be demonstrated; 3, the inertia potential energy of earth time rotational can be demonstrated.
