Description

Technical field: [0001] The content of the invention belongs to the field of electromagnetic technology, and relates to a pulse generating device, especially a pulse strong magnetic field generating device. Background technique: [0002] Compared with electric field, magnetic field has better penetration to biological tissue. Irradiating biological tissue with pulsed magnetic field can produce many biological effects, such as stimulating motor nerves and detecting the state of nerves; inducing ferromagnetic nanomaterials at the target to generate heat, killing Dead cancer cells; promote cell membrane rupture, cell fusion, etc. [0003] In the existing pulsed magnetic field generating device, in order to generate a relatively strong magnetic field, a ferromagnetic material with high magnetic permeability is added to the coil. The rising edge of the pulsed magnetic field is relatively slow, which is quite different from the ideal rectangular pulsed magnetic field; secondly, d...
