specinho + 440 April 16 (edited) Someone at NASA got this shot of total solar eclipse... It gives us an insight into another less explored side of earth i.e. the earth itself is a magnet, with current flowing constantly from north pole to south. And south to north? If this image is true, 1. theory of magnetism is about to change? (Refer to image magnetic field. The flow is one direction, from north to south only...) 2. theory of wireless electricity generation or sky- letric is about to be realized or popularized?

Upper end = North; Lower end = South The tilting angle indicates it is summer or autumn in the South. 2. Cloud formed at both sides of sphere indicate electro-magnetic field. - c, a shape on the left side showing a flow of electrons from North to South - ') a shape on the right side showing a flow of electrons from South to North. (Uncertain if this is correct. Looking at the direction of cloud, it appears to be...) P/s: normal magnet has one directional flow i.e. from North to South. Therefore, the earth itself is a " hermaphrodite" i.e. a) it is a naturally formed magnet b) it has current flowing in one complete circle constantly. ( Uncertain about this one... Normal theory, two circuits on the side...) By intercepting this current, electricity can be obtained? I.e. sky- letric. (Uncertain about this one. If too much interception, protection onto the earth against cosmic rays would be weaken...?) A country in Scandinavia has a wireless electric car charging lane. Not sure how they did it... This was a random video shown by world economic forum page on facebook... Could it be intercepting current from the sky?? Quote Share this post Link to post Share on other sites

Yes, any moving conductor in a magnetic field (or a stationary conductor in a changing magnetic field) will induce a current. However, the earths magnetic field strength is so weak that you can't really harness much energy from it. It is strong enough to turn a small floating needle in a compass, but that is about it. For comparison a rare earth magnet can produce a field strength of 1.2 T. The earth produces a field strength of 25 to 65 μT. Several orders of magnitude difference. Hospital MRI units run at >1.5T, fancy units near 7T. Edited April 17 by TailingsPond 1 Quote Share this post Link to post Share on other sites

Hospital MRI units run at >1.5T, fancy units near 7T. Thank you for the info. There is another aspect that could be expanded in discussion.. But i'm not certain it is correct.... 1. As a " hermaphrodite", the earth has both a) magnetic field, formed by compound of iron, Fe. - There is an appearance of axis from the North near Hudson bay, to the South, a village of Argentina, with the most frequent lightning hit per year. b) electric field, most probably formed by flowing magma and positively charged minerals in the core ( or larva when out of earth crust). The flow of conductors ( metal ions) is constant, from hot core to colder areas on the crust. p/s: posted a link copied from facebook regarding a video and discussion of this. Not sure if anyone has seen it... 2. When the earth is self spinning, probably caused by the tilt of axis and flowing magma, electro-magnetic field is produced. a) positively charged ions or ionic compound attract electrons from the sun 🌞 i) This inflow of electrons shall conducted would become electricity? ii) solar panel is using photon, energy pack of the sun to jump start a flow of electron from atom silicone? (i) is direct conduction like a lightning rod... But...... It is collecting small amount at fixed location to become accumulated large sum or be amplified... However, b) electro-magnetic field on earth repels those incoming electrons... - only electrons with certain frequency or wavelength are allowed. - refraction of light by prism, water droplets, cloud proves that electron of different frequency produces different colour of light. - with that, aurora or polar light, hence, is merely a refraction of light by the cloud or water droplets in the sky?? - harvesting certain colour of light would give certainty of electricity at certain frequency?

The earth does not attract particles from the sun. The sun shoots out high energy particles called solar wind. https://en.wikipedia.org/wiki/Solar_wind The magnetic field primarily deflects solar wind particles away from the earth. The portion of solar wind the magnetic field fails to deflect is what causes the northern lights. Not refraction. Yes, harvesting a a certain colour (frequency) of light does produce an ejected electron of a specific energy (the photoelectric effect). This is how standard solar panels work. https://en.wikipedia.org/wiki/Photoelectric_effect Quote Share this post Link to post Share on other sites
