Recombination and bremsstrahlung radiation yields from strong field rescattering of 9x10{sup 14} W/cm{sup 2} (Ne{sup +}) to 3x10{sup 17} W/cm{sup 2} (Ne{sup 8+}) photoelectrons show the laser magnetic field alters the rescattering dynamics for fields beyond one-atomic unit of field (3x10{sup 16} W/cm{sup 2}). At 3x10{sup 16} W/cm{sup 2}, the deflection of the rescattering wave begins to exceed its transverse width and the yields of photons with energies above 100 hartree of energy (2.7 keV) are attenuated. Radiation at 3x10{sup 17} W/cm{sup 2} (Ne{sup 8+}) is suppressed by 10{sup 2} for the highest energy photons near 1000 hartree and by 10{sup 5} for lower energy in the range of 10-100 hartree.
