German scientist and philosopher who made fundamental contributions to physiology, optics, electrodynamics, mathematics, and meterology.Ī pair of conducting circular coils each having N turns, each carrying a current I, separated by a distance equivalent to the radius of the circular loops, produce a homogeneous magnetic field B in the mid-plane between the two circular coils.Ī magnetic field is created whenever charge is in motion-either moving in space or spinning around itself.
