"Web9. júl 2024 · When the pulse is over, the polar magnetic field reflects and suddenly collapses, causing a sharp electrical rise. This rise continues for a few microseconds (a millionth of a second) and causes another current to pass through the coil. This current is called the reflected pulse and is very short and lasts only about 30 microseconds. " - Reflected pulse
