Magnetic methods are more popular in mineral exploration than gravity, not least because magnetic data can be quickly recorded from the air and in conjunction with other geophysical surveys. Land gravity surveys, by contrast, may require greater field efforts (Figs. 1, 5 and 6), more time, and more commitment of scarce capital.

Thus, at 5A the iron content in the concentrate is only 1.5% more than its content in the original ore. Iron content in the concentrate increases considerably with the further increase of the current strength because iron ore particles with a low magnetic susceptibility (ore aggregates) begin to separate in the technological process.
