Recent experimental and theoretical investigations are reviewed concerning the generation of fast charged particles and superstrong magnetic fields in the interaction of ultrashort laser pulses with solid targets. The mechanisms of generating fast charged particles in superstrong light fields of
laser radiation with intensities ranging from 1017 to 1021 W cm-2 are considered. Electron acceleration due to vacuum heating, the ponderomotive potential, resonance absorption, the laserdriven wake field in the underdense part of plasma, cyclotron
mechanism and some other mechanisms are thoroughly analyzed. Experimental data on the acceleration of protons and atomic ions by spatial charge fields on thin and thick solid targets are presented and theoretically interpreted. Particular attention is paid to the generation of superstrong quasistatic
magnetic fields in laser plasmas and methods for measuring them under the action of various laser pulses of both femto- and picosecond durations. The possible formation of magnetic plasma configurations and magnetic plasma confinement are discussed.
