Analysis of the pinning interaction in high-temperature (HTc) superconductors is presented. The model based on analysis of the enhancement of the energy of a superconductor under the vortex motion against its equilibrium position is described. The influence of the dimensions of pinning centres and of the elasticity forces of the vortex lattice on the critical current is considered. The magnetic induction profiles in HTc superconductors are obtained, taking into account the granular structure of ceramic materials, while the flux trapped is determined. The magnetic hysteresis losses, modified by the existence of the magnetic nickel substrates in HTc tapes of second generation are considered too.
