Power lines and radiation protection

The greater use of renewable energies from solar and wind requires the expansion of the electricity grids. Radiation protection plays an important role in this because electric and magnetic fields are generated by additional high-voltage lines. How great are possible loads from high-voltage lines? W

Earth's magnetic field

You can imagine Earth’s magnetic field as if there were a giant bar magnet inside the planet. Because it has two poles, it’s called a dipole. Around such a magnet, so-called field lines form. Authors: ZDF/Terra X/Bilderfest/Tillman Graach/Moritz Krause/Benjamin Calliari-Herzberg/Maximilian Heß Tra
