AI Technical Summary

Problems solved by technology

[0003] The magnetic induction intensity of the uniform magnetic field directly affects the decompression effect in the cylinder. The uniform magnetic field inside the cylinder can be realized by adding an energized densely wound solenoid on the outer wall of the cylinder. A metal cylinder made of steel will inevitably have an external magnetic field It produces shielding effect, and the induced current formed on the surface of the cylinder under the excitation of alternating current will also weaken the external excitation magnetic field, thereby having a great impact on the distribution of the equivalent magnetic field in the bore, making it difficult to judge the change law of the magnetic field inside the cylinder
