Magnetic Field Generators | How it works, Application

What are Magnetic Field Generators? A magnetic field generator is a device used to create a magnetic field. This field can be static (as in a permanent magnet) or dynamic (as in an electromagnet). A magnetic field generator typically includes a magnet or an electrical current source, and a magnetic core that concentrates the magnetic field.

Geomagnetic solar flare effects: a review | Journal of Space

Solar flare effects (Sfe) are rapid variations in the Earth''s magnetic field and are related to the enhancement of the amount of radiation produced during Solar flare events. They mainly appear in the Earth''s sunlit hemisphere at the same time as the flare observation and have a crochet-like shape. Solar flare effect on the geomagnetic

2. Loss of reactive power support, which could lead to voltage instability and power system collapse. For extra high voltage (EHV) transformers, the effects of GIC include half-cycle saturation that results in: 1) harmonic currents, 2) fringing magnetic fields (flux that flows outside the core), and 3) increased reactive power (VAr) consumption.
