Problems solved by technology

From the perspective of bioelectric effect, the action of magnetic field causes the change of intracellular magnetic flux and induces current on the cell membrane, and the electromotive force generated between the induced current and the external strong pulsed magnetic field destroys the cell membrane; the charged particles in the cell are stimulated by the magnetic field. Under the influence of Lorentz force, its trajectory is often restricted within the Larmore radius, resulting in the abnormal transmission of electrons and ions in the cell, which affects the transmembrane potential of the cell membrane and the concentration of free calcium ions in the cell, thereby affecting the cell's normal physiological function
