Although there have been tantalizing events recorded, in particular the event recorded by Blas Cabrera on the night of February 14, 1982 (thus, sometimes referred to as the "Valentine's Day Monopole"), there has never been reproducible evidence for the existence of magnetic monopoles.
Kuigi on vaadeldud ärevusttekitavaid sündmusi, eriti Blas Cabrera poolt 14. veebruaril 1982 registreeritud sündmus (nn valentinipäeva monopoolus), ei ole tänase päevani õnnestunud leida magnetpooluste olemasolu kohta reprodutseeritavaid tõendeid.
