The spectral shapes of the {sup 12}B and {sup 12}N beta decays have been measured with a beta spectrograph specifically designed to examine the spectral effect of weak magnetism. Writing the weak magnetism correction to the beta spectra as (1+{alpha}{sub {plus minus}}{ital E}) we find the difference {alpha}{sub {minus}}{minus}{alpha}{sub +}=(1.24{plus minus}0.42)%/MeV, in agreement with the conserved vector current prediction.
