Why is a current carrying loop considered a dipole?

WebNov 5, 2024 · If a closed loop carries a current, I, the magnetic dipole moment vector, μ →, is defined such that it has a magnitude: μ = I A where, A, is the area enclosed by the loop. The direction of the magnetic dipole moment vector is such that it is perpendicular to the surface defined by the loop. WebIn classical physics, the magnetic field of a dipole is calculated as the limit of either a current loop or a pair of charges as the source shrinks to a point while keeping the magnetic moment m constant. For the current loop, this limit is most easily derived from the vector potential: = =,where μ 0 is the vacuum permeability constant and 4π r 2 is the … going to the gym while on my period
