The magnetic field strength and plasma parameters (density, velocity, and temperature) measurements are global properties of CMEs among others, which help in shaping the understanding of what CMEs were, are, and will be. As CMEs propagate in the heliosphere, these properties vary; hence, the need to investigate the dependence of CMEs’ properties over different heliocentric distances. We used the HELIO4CAST catalog to examine more than 1600 CMEs between 0.2 and 2.2 AU. Performing minimum variance analysis on RTN and MVA coordinate systems, we observe that both the poloidal and the toroidal magnetic field components show a consistent decrease in strength as a function of heliocentric distance from the sun with a similar power law index.
