  • Blackett's original formula was an attempt to correlate the known magnetic fields of large rotating bodies, such as the Sun, Earth, and a star in Cygnus whose field had been measured indirectly.[1] It was unusual in that it brought Isaac Newton's gravitational constant and Coulomb's constant together, the one governing forces between masses, the other governing forces between electric charges.
