  It is proposed that Magnetic Monopoles (MMs) could originate from a new
$\mbox{U(1)}_{M}$ symmetry. Such an abelian symmetry is then assumed to be
related to the conservation of a magnetic number $M$. This magnetic number is
associated with massive MMs from an expected high scale breaking of this
magnetic symmetry. The involved scales are approached and the properties of
such MMs are investigated along with the prospects for their detection.
