Abstract
A magnetic liquid countdown apparatus is applicable to various occasions of countdown activities, and comprises an electromagnetic cavity (1), a transparent cavity (2), deionized water (3), magnetic liquid (4), an electromagnet (5) and a controller (6), wherein the controller (6) controls power on/off of the electromagnet (5). When the electromagnet (5) is powered on, the magnetic liquid (4) moves upward to the powered-on electromagnet (5) under the magnetic field gradient effect and stably attaches to the electromagnet (5), and the electromagnet (5) under power-off state may not attract the magnetic liquid (4). When the electromagnet (5) is powered off, the magnetic liquid (4) loses magnetism due to soft-magnetic characteristic and returns to the lower portion of the transparent cavity (2). The controller (6) controls the electromagnet (5) to change power-on/off state every second to realize the countdown function.

Detailed description of the invention
With accompanying drawing 1 to accompanying drawing 5, for detailed description of the invention, the invention will be further described:
A kind of magnetic liquid inverse timing device, this device includes: electric magnet cavity 1, transparent cavity 2, go from
Sub-water 3, magnetic liquid 4, electric magnet 5, controller 6.
Connection between this device each several part:
First magnetic liquid 4 is injected into the bottom of transparent cavity 2, is subsequently adding deionized water 3, magnetic liquid
The density of body 4 is more than deionized water 3, and the two is immiscible, and therefore magnetic liquid 4 is positioned at transparent cavity 2
Bottom, deionized water 3 is positioned at the top of transparent cavity 2；Then electric magnet 5 is spliced into numeral " 8 "
Shape, is fixed on the front panel of electric magnet cavity 1, then is connected with controller 6 by electric magnet 5, each
Electric magnet can work independently, and controller 6 is placed in the inside of electric magnet cavity 1；Finally will be fixed with
The front panel of the electric magnet cavity 1 of electric magnet 5 and transparent cavity 2 are spliced into one, as shown in Figure 1.
Controller 6 can control energising and the power-off of electric magnet 5, when electric magnet 5 is energized, due to magnetic
Liquid 4 has response to magnetic field, and the magnetic liquid 4 of the most transparent cavity 2 bottom is by the effect at magnetic field gradient
Under be moved upward at the electric magnet 5 that is under "on" position and stable absorption, be not under "on" position
Electric magnet 5 will not adsorb magnetic liquid 4, when after electric magnet 5 power-off, due to the soft magnetic characteristic of magnetic liquid 4,
To lose magnetism immediately, return to the bottom of transparent cavity 2；Owing to electric magnet 5 is spliced into the shape of numeral " 8 "
Shape, thus can control electric magnet 5 by controller 6 and convert once electrification mode each second, so that
Magnetic liquid 4 realizes the different shapes such as numeral " 9 ", " 8 ", " 7 ", " 6 " in transparent cavity 2,
Achieve the function of countdown.
As shown in Figure 2 give electric magnet 5 be numbered, numbered " 1 " to " 20 ", when numbered " 1,2,
3,4,5,6,7,8,9,10,11,12,14,16,17,18,19,20 " electric magnet is in
"on" position, the electric magnet of numbered " 13,15 " is in when being not powered on state, and magnetic liquid is at transparent chamber
The internal numeral that presented is for " 9 ", as shown in Figure 3；When numbered " 1,2,3,4,6,8,9,10,
11,12,14,16,17,18,19,20 " electric magnet is in "on" position, numbered " 5,7,
13,15 " electric magnet is in when being not powered on state, and it is " 3 " that magnetic liquid is presented numeral in transparent chamber body,
As shown in Figure 4；When numbered " 1,2,3,4,6,8,9,10,11,12,13,15,17,18,
19,20 " electric magnet is in "on" position, and the electric magnet of numbered " 5,7,14,16 " is in and does not leads to
