Specifically, when the optical fiber 1 is well sealed, the gold particles 4 receive their own downward gravity, and the magnetic thin film 5 receives an upward attraction force because the upper surface of the upper layer is an N-pole. Also, since the lower surface of the lower layer is an N-pole, the lower layer is subjected to an upward repulsive force. The upward force is equal to the downward force, and the gold particles 4 will remain in a stable state and float in the air. The first conductor 6, the second conductor 7, the third conductor 8 and the fourth conductor 9 are fixed, the ammeter 10 is shown as 0, and the alarm device does not work.

When optic fibre 1 was damaged, optic fibre 1 had the light leakage, and the light that leaks out shines on gold granule 4, and gold granule 4 surface can produce the light and heat effect, and heat can make gold granule 4 surface expansion to can make even the magnetic film 5 on gold granule 4 surface to stretch out and draw back from top to bottom. At this moment, the attractive force received by the upper layer and the repulsive force received by the lower layer are increased, the direction is upward, the stable states of the gold particles 4 and the magnetic film 5 are damaged, the gold particles 4 move upward, after the upward movement, the gold particles 4 do not have a photo-thermal state any more due to the opaque characteristic of the upper part, the heat is not generated any more, the gold particles are contracted to be in an original state, and at this moment, the gold particles 4 move downward. Under the action of magnetic field force and inertia, the gold particles 4 do up-and-down oscillating motion.

When the gold particles 4 move up and down, the air pressure in the transparent container 3 changes, and when the gold particles move up, the upper air pressure increases and the lower air pressure decreases. The change in gas pressure will cause the first conductor 6 and the second conductor 7 to move to both sides and the third conductor 8 and the fourth conductor 9 to move to the middle. Conversely, downward movement causes the first and second conductors 6, 7 to move towards the middle and the third and fourth conductors 8, 9 to move to the sides. The conductor movement cuts the magnetic induction lines, and according to the right hand rule, downward current is generated in the conductor moving towards the middle, and upward current is generated in the conductor moving towards the two sides. The current collection is collected in the ammeter 10, and when current exists in the ammeter 10, the alarm device gives an alarm.
