1) Magnetic poles at the ends of a long bar magnet
are the nearest analogies (in my mind) of monopoles.
2) Bound electric charges at the end of a long electret
are related to free charges as magnetic poles are related
to monopoles, except that monopoles, as far as we
know, do not exist.
3) An electret can be made by melting an appropriate
wax in a glass tube and by allowing it to solidify in a
strong electric field parallel to the tube's axis.
4) I have no doubt that a stationary magnetic needle
will detect additional magnetic field when one end of
the electret rod is moved rapidly near it (while another
end is as far away as possible).
5) Likewise, a rapidly moving magnetic pole (the end
of a long bar magnet) will probably create an additional
electric field detectable by a stationary electric dipole
("electric compass" needle.)
