The excitation coil excitation permanent magnet energy device of the invention is further described in detail with reference to the accompanying drawings.

With reference to fig. 1, an excitation coil excitation permanent magnet energy device includes a U-shaped magnetic medium 2 and a permanent magnet 1 disposed between two ends of the U-shaped magnetic medium 2, two sides of the U-shaped magnetic medium 2 are surrounded by a first external magnetic medium 3 and a second external magnetic medium 4 to form a semi-closed region, one ends of the first external magnetic medium 3 and the second external magnetic medium 4 close to an opening of the semi-closed region are respectively provided with a first moving magnet 5 and a second moving magnet 6, a first coil 9 is wound outside one side of the U-shaped magnetic medium far from the first moving magnet 5, two ends of the first coil 9 are connected with a first ammeter 11 through a lead, a second coil 10 is wound in the middle of the U-shaped magnetic medium, and two ends of the second coil 10 are connected with a second ammeter 12, a switch 14 and a power supply 13 through leads in series.

In a preferred embodiment of the present embodiment, one end of the first moving magnet 5, which is far from the first external magnetic medium 3, is connected to a first bolerometer 7, and one end of the second moving magnet 6, which is far from the second external magnetic medium 4, is connected to a second bolerometer 8.

As a preferred embodiment of this embodiment, the first external magnetic medium 3 and the second external magnetic medium 4 are configured as an L-shaped structure.

In the specific implementation of the invention, the upper end of the permanent magnet 1 is set as an N pole, the lower end is set as an S pole, when the switch K is closed, the second coil 10 is connected with a power supply to generate current, the right-hand spiral rule is obtained, the upper end of the U-shaped magnetic medium 2 surrounded by the second coil 10 is the N pole, the lower end is the S pole, the upper ends of the permanent magnet 1 and the U-shaped magnetic medium 2 are both N poles, the direction of the magnetic induction line of the magnetic field excited by the second coil 10 is opposite to the direction of the magnetic induction line of the permanent magnet 1, when the magnetic fluxes of the magnetic fields of the permanent magnet 1 and the U-shaped magnetic medium 2 are equal, the magnetic field of the permanent magnet 1 is prevented from passing through the U-shaped magnetic medium, namely the second coil 10 plays a role in exciting an opposite magnetic field, the potential energy of the magnetic field in the stable state of the permanent magnet 1 is forced to be excited, the magnetic, the magnetic field is changed from one direction to the other direction, the first outer magnetic medium 3 and the second outer magnetic medium 4 have magnetic fields to pass through, so that the first moving magnet 5 and the second moving magnet 6 are adsorbed under the magnetic action of the magnetic field, the acting force of the bolthometer is overcome, useful mechanical work is output, and the magnitudes of the forces F1 and F2 can be read from the pointer of the bolthometer.

When the switch K14 is turned off, no current passes through the second coil 10, no magnetic field is generated in the U-shaped magnetic medium, the moving magnet body above the first external magnetic medium 3 and the second external magnetic medium 4 is pulled away and moves upward under the action of the bolerometer, which indicates that the magnetic field of the permanent magnet 1 no longer acts on the first external magnetic medium 3 and the second external magnetic medium 4 and turns to the U-shaped magnetic medium 2, and the initial stable state is recovered.
