Weber) *1 weber/meter-squared= one tesla (t) -------------------------------------------------------------------------- *English uses the gauss (G) (after Johann Karl Friedrich Gauss,1777-1855 ) *one gauss= 6.452 lines (magnetic flux)/inch-squared) *10,000 gauss= one tesla(T) -------------------------------------------------------------------------- *MKS uses the tesla (T)(after Nikola Tesla 1857-1943) *one tesla(T)= one weber/meter-squared *one tesla(T)= 10,000 gauss *the 'nanotesla' is used in Earth lithosphere seismology as a unit of measure with magnetometers,associated with seismomagnetic offsets @ epicentral distances,and piezomagnetic effects,and tectonomagnetic effects ------------------------------------------------------------------------- *The magnetic field strength between the Sun and Earth is inversely proportional to the square of the distance in between them,or,follows an inverse-square relationship. *Since Earth follows an elliptical orbit around the Sun,the magnetic field strength varies as the orbital distance varies *Since Earth's orbital ellipticity also varies with one of the three Milankovitch cycles,the magnetic field strength is also coupled to this cycle. __________________ Photobucket album: http://s1271.photobucket.com/albums/jj622/aerohead2/ Last edited by aerohead; 08-30-2018 at 01:54 PM..
