To put magnetic strengths in perspective, here is a table of magnetic field strengths
The Earths magnetic field, which deflects compass needles (measured at the N magnetic pole) 0.6 Gauss
A common iron magnet like those used to stick papers on a refrigerator 100 Gauss
The strongest fields achieved so far in the laboratory Sustained (steady) 4 X 105 Gauss
The strongest fields achieved so far in the laboratory Ephemeral (made using explosives; lasts only milliseconds) 107 Gauss
The maximum field observed on ordinary stars - 106 Gauss
Typical magnetic field of radio pulsars (the ordinary, familiar kind of neutron star; (hundreds are known to astronomers) 1012 Gauss
Magnetars (soft gamma repeaters) 1014 - 1015 Gauss
