Embodiment
The magnetic suspension train principle demonstration instrument, as shown in Figure 1, comprise base box 1 and be positioned at the action of a magnetic field power experiment package in base box the place ahead and the magnetic levitation simulated experiment assembly of base box top, be separately installed with the first electromagnet power supply switch 13 and the second electromagnet power supply switch 14 on the base box 1, and two power lights 15.Wherein the action of a magnetic field power experiment package comprises second electromagnet 2 that is fixed in base box 1 left forward side, is fixed in the brace table 3 on right side and is loaded on second glass bar 5 between second electromagnet 2 and the brace table 3, have glass bar jack 6 on the brace table 3, be with a pair of opposite polarity circular magnet 7 on second glass bar 5, second glass bar locking catch 4 is installed on the brace table 3.
The experiment that utilization the action of a magnetic field power experiment package is done is as follows: [experiment 1] splits both sides relatively with the circular magnet heteropole, promotes one, and very fast armful of two magnet together.Then their homopolarities are split relatively both sides and promote one, two magnet repel mutually.[experiment 2] unloads second glass bar, holds up and inserts in the glass bar jack, tests once more according to said method, and relative as homopolarity, a magnet will suspend in the air.[experiment 3] inhales two magnet heteropoles together relatively, be through second glass bar on relative with the second electromagnet homopolarity, will the glass bar horizontal, two magnet are split both sides, press the second electromagnet power supply switch, energized, second electromagnet produces powerful magnetic force at once, to push another side at a gallop to against its circular magnet, embrace together with another piece.
Magnetic levitation simulated experiment assembly comprises support 8, vertically is loaded on first glass bar 9 in the middle of the support and be placed in annular small magnet 10 and position revolving coil 11 thereon on first glass bar, also comprise first electromagnet 12 that is installed in the base box 1, first glass bar, 9 lower ends are equipped with first glass bar locking catch 16 over against first electromagnet, 12 centers on the support 8.
The experiment that utilization magnetic levitation simulated experiment assembly is done is as follows: [experiment 4] presses the first electromagnet power supply switch, and the annular small magnet that first electromagnet generation powerful magnetic force will be relative with its homopolarity holds up and is suspended in the air.Under the action of a magnetic field, the very fast rotation of revolving coil is got up.[experiment 5] opens the locking catch of first glass bar, extracts glass bar, removes revolving coil, and glass bar is loaded onto again, presses the first electromagnet power supply switch, and the powerful magnetic force that first electromagnet produces is pushed to cantilever tip with annular small magnet.As Push switch repeatedly, annular small magnet can be as the spring trampolinist, and ceaselessly motion up and down is very much interesting on glass bar.
