Muchidimbu, pfungwa yaLorentz yakashoropodzwa naAbraham, uyo akaratidza kuti kune rumwe rutivi dzidziso yacho inoteerera mutemo wehukama, uye kune rumwe rutivi mavambo emagetsi emagetsi emasimba ose anotorwa. Abraham akaratidza, kuti zvose zviviri zvaive zvisingawirirani, nokuti muLorentz dzidziso yemagetsi akabatanidzwa, masimba asiri emagetsi aidiwa kuti ave nechokwadi chekugadzikana kwechinhu. Zvisinei, mune dzidziso yaAbraham yeiyo electron yakaoma, hapana masimba akadaro aidiwa. Nokudaro mubvunzo wakamuka kana maonero eElectromagnetic yenyika (anowirirana neAbraham's theory) kana kuti Relativity Principle (inowirirana neLorentz's Theory) yakanga yakarurama. Mune hurukuro muna September 1904 inonzi St. Louis The Principles of Mathematical Physics, Corincaré akawana tsanangudzo inokosha kubva kumitemo yemagetsi emagetsi emagetsi emagetsi nemasimba ose anotorwa.
