State unit and dimension of magnetic dipole moment
Answers
A magnetic dipole is the limit of either a closed loop of electric current or a pair of poles as the dimensions[clarification needed] of the source are reduced to zero while keeping the magnetic moment constant. It is a magnetic analogue of the electric dipole, but the analogy is not perfect. In particular, a magnetic monopole, the magnetic analogue of an electric charge, has never been observed. Moreover, one form of magnetic dipole moment is associated with a fundamental quantum property—the spin of elementary particles.
Explanation:
Magnetic Moments and Dipoles. ... The magnetic dipole moment (µ) is a vector defined as µ = i A whose direction is perpendicular to A and determined by the right-hand rule. Like a compass needle, the magnetic moment (µ) will seek to align with an externally applied magnetic field (Bo).
