The magnetization curves M(H) for ideal type-II superconductors and the maximum, minimum, and saddle-point magnetic fields of the vortex lattice are calculated from Ginzburg-Landau theory for the entire ranges of applied magnetic fields H(c1)less than or equal toHless than or equal toH(c2) or induction 0less than or equal toBless than or equal tomu(0)H(c2) and Ginzburg-Landau parameters 2(-1/2)less than or equal tokappaless than or equal to1000. Results for the triangular and square flux-line lattices are compared with the results of the circular cell approximation. The exact magnetic field B(x,y) and magnetization M(H,kappa) are compared with often used approximate expressions, some of which deviate considerably or have limited validity. Useful limiting expressions and analytical interpolation formulas are presented.
