As an embodiment of the present invention, the course of work of gravitation bringing device, the poles N exist when shape of a hoof magnet steel 12 is installed
On, the poles S under, to coil according to such as Fig. 4 a, the direction 4b, 4c be powered, according to Ampere theorem, coil in ungulate permanent magnet understand by
To the effect of power；
When the hot-wire coil and perpendicular magnetic induction intensity that the number of turns is N, the power F that hot-wire coil is subject in magnetic field meets
Following formula：
F=NBIL
Wherein B is the magnetic induction intensity in magnetic field；I is the current strength detected in conducting wire；L is the effective length for detecting conducting wire
Degree；N is coil turn；F is the Ampere force for detecting conducting wire and being subject in magnetic field.According to Newton's third law, the two of interaction
Active force between object is always equal in magnitude with reaction force, direction is opposite, effect on the same line.Therefore suffered by magnetic field

Power, that is, coil is also different to the force direction in magnetic field, to simulate the variation of Mars gravity direction；
When coil and the position relationship in magnetic field as shown in fig. 4 a when, the both sides b, d of coil enter the length in magnetic field, in coil
Electric current, place magnetic field intensity size be equal, but sense of current is on the contrary, so Ampere force F that the both sides b, d are subject to2、
F3Direction equal in magnitude is on the contrary, offset, and resultant force F and reaction force (the Mars gravitation of simulation) F ' that entire coil is subject to is as schemed
It is 5a, shown, wherein：

Show, wherein：
F '=- F
F=F1+F2,
F2=F1 2+F2 2
Because magnetic field where coil is equal in magnitude, size of current is equal in coil, therefore can be by changing the side b, c in magnetic
Length in changes the both sides b, c by Ampere force F1、F2Size, to change angle, θ, that is, change simulation Mars gravitation
Direction；
When coil and the position relationship in magnetic field as illustrated in fig. 4 c when, the both sides a, b outside magnetic field, suffered Ampere force be 0,
C, the both sides d are by Ampere force F1、F3, the resultant force F suffered by coil and reaction force (the Mars gravitation of simulation) F ' such as Fig. 5 b institutes
Show, wherein：
F=F1+F3,
F2=F1 2+F3 2
Similarly, because magnetic field where coil is equal in magnitude, size of current is equal in coil, therefore can be by changing c, d
While length in magnetic field changes the both sides c, d by Ampere force F1、F3Size, to change angle [alpha], that is, change simulation fire
The direction of star gravitation.
