I read somewhere that only electric currents generate magnetic fields.

That is incorrect. The intrinsic spins of elementary particles also
produce magnetic fields.

the charged leptons. *K-K posits that a 4th spatial

Planck Length and the electron moves at a constant velocity

now for your information

the electron does not orbit all around the nuc !!
b

the formulas of an orbiting object
are exacty as those of a VIBRATION HARMONICALLY

object!!
so according to my new findigs about nuclear and Atomic structure

the electron does not orbit
BUT VIBRATE
sort of a vibration of a rodd or a string!!

"current" that causes the magnetic dipole moment of the
electron and hence "permanent magnets" so called.
* *Yablon is a highly competent mathematical physicist and
his paper has been reviewed by Phys. Rev. *I have read the
review (wch. was posted on s.p.r.) and apparently they
rejected the paper solely on the grounds that the idea was

anyone can see is a quite inadequate and unfair response!

i dont know about that specific case but
simple is not a disadvantage
quite the opposite (:-)
