If magnetic monopoles had relatively small masses, the particles would sap
the strength of magnetars» magnetic fields.
In the units used by physicists,
the strength of a magnetar's magnetic field is about a million billion Gauss; a refrigerator magnet has a field of about 100 Gauss.
Not exact matches
Magnetar fields reach
strengths a thousand times stronger still, and scientists don't know the details
of how they are created.
