We consider a relativistic , degenerate , electron gas under the influence of a strong magnetic field , which describes magnetized white dwarfs .
Landau quantization changes the density of states available to the electrons , thus modifying the underlying equation of state .
We obtain the mass-radius relations for such white dwarfs and show that it is possible to have magnetized white dwarfs with a mass significantly greater than the Chandrasekhar limit in the range 2.3 - 2.6 M _ { \odot } .
Recent observations of peculiar type Ia supernovae - SN 2006gz , SN 2007if , SN 2009dc , SN 2003fg - seem to suggest super-Chandrasekhar-mass white dwarfs with masses up to 2.4 - 2.8 M _ { \odot } , as their most likely progenitors and interestingly our results lie within the observational limits .
