They are the fundamental units of magnetism A number of different units for expressing magnetic dipole moment (hereafter simply “magnetic moment”) are commonly seen in the literature, including, for example, erg introduced when The magnetic dipole moment is a measure of the strength and orientation of a magnet or current loop in a magnetic field. The field lines come out of the north pole and curve out and around to the south pole. In the macrocosm, the exact dipole is really a spherical current distribution and the simple loop is a good dipole approximation at fairly large distance, see Sect. 2 Analogy Between Simple Harmonic Oscillator and LC Circuit. The magnetic moment μ ‾ \overline{\mu} μ of a magnet is a measure of the strength and direction of the magnetic field it produces.

Physics A pair of separated electric charges or magnetic poles, of That’s why we call the loop a magnetic dipole. It is natural to think of electrons circulating around a nucleus as comprising a circulating current, and hence giving rise to a magnetic moment Dipole can mean two things in physics. The magnitude of a magnetic dipole moment or magnetic moment . This is a vector quantity, and the torque is a maximum when the dipole We define the magnetic dipole moment as the area vector times the current of the loop. It describes the strength and orientation of a magnetic source with Magnetic Moment: a vector quantity that is a representation of the torque produced on a magnetic system (such as a bar magnet or dipole) when put in a magnetic field, and is the product of the magnetic dipole, generally a tiny magnet of microscopic to subatomic dimensions, equivalent to a flow of electric charge around a loop.
