The nonthermal effects on the Karpman-Washimi ponderomotive magnetization are investigated in Lorentzian plasmas. The induced magnetization due to the nonstationary ponderomotive interaction related to the time variation of the field intensity is obtained as a function of the Debye length and spectral index. It is shown that the nonthermal character of the Lorentzian plasma suppresses the cyclotron frequency due to the ponderomotive interactions. It is also shown that the Karpman-Washimi magnetization enhances with increasing the spectral index and scaled wave number. In addition, it is found that the ponderomotive magnetizations in Lorentzian plasmas are always smaller than those in Maxwellian plasmas due to the nonthermal effects. It is also shown that the nonthermal character strongly suppresses the total energy radiated due to the Karpman-Washimi ponderomotive force in Lorentzian plasmas.
