How Does Jupiter's Magnetic Moment Relate to Ancient Thunderbolt Weapon Symbolism?

The planet Jupiter has Magnetic Moment  = 2.83 x  1028   N. m³  at  60 million–140 million amps .   Pliny wrote: " .. thunderbolts proceed from the three superior stars , but principally from the one which is situated in the middle . . . and hence it is commonly said, the thunderbolts are darted by Jupiter". .  The electrical discharge from a planet is described very clearly by Pliny: “heavenly fire is spit forth by the planet as a crackling charcoal flies from a burning log.”  _ Pliny, Natural History (London, 1865), Book. Ii, ch. 18.This thunderbolt is from Bali Indonesia 14th cent. and resembles the Greek  weapon of Zeus Jupiter.https://www.google.com/search?q=thunderbolt+bali+museum+14th+century&rlz=1C1CHFX_enAU797AU797&sxsrf=ACYBGNSK9Cn0sjBSooZzbs2R5Qh3OLtmnw:1573801979556&source=lnms&tbm=isch&sa=X&ved=0ahUKEwiOusCf1evlAhVJWH0KHWdFBNAQ_AUIEigB&biw=1024&bih=625#imgrc=ltWDaGaMaPAawM:  
It is  480mm and about .8kg mass . Jupiter's gravity is 2.5 G .  Lorentz force has vector matching Jupiter's spin. Kelvin-Helmholtz wave instability allows some particle transit.  What electrical charge system will this thunderbolt need to  be fired from Jupiter to Earth?

The system for doing that wouold be impossible to build . The charge should cross the universe path to arrive on the earth with the same intensity of lightning, if I have understood well the problem

Thank you Maurizio,The idea is to charge the metal weapon and impel this object by Lorentz force.On Jupiter "Electric voltages of about 10 million volts, and currents of 10 million amps -- a hundred times greater than the most powerful lightning bolts -- are required to explain the X-ray observations ".  NASA.
  "A typical lightning bolt contains 1 billion volts and contains between 10,000 to 200,000 amperes of current."  
  "The initial cloud potential for negative lightning is typically in the range of 50 - 100 million volts."   A transformer supplies the charge at 100 x 10^12   W .
