Magnetic moment - Wikipedia
WEBIn electromagnetism, the magnetic moment or magnetic dipole moment is the combination of strength and orientation of a magnet or other object or system that exerts a magnetic field. The magnetic dipole moment of an object determines the magnitude of torque the object experiences in a given magnetic field.
Magnetic Moment - Definition, Formation, Magnetic Dipole …
WEBMagnetic moment, also known as magnetic dipole moment, is the measure of the object's tendency to align with a magnetic field. The objects have a tendency to place themselves in such a way that the magnetic moment vector becomes parallel to the magnetic field lines.

WEBAug 12, 2024 · The magnetic moment starts at an angle of 90º with the field, and ends at an angle of 0º: \[\Delta U_{mag} = \left(-\mu B \cos 0^o\right) - \left(-\mu B \cos 90^o\right) = -IAB = -I \left(0.54\;m\right)^2\left(1.2\;T\right) = -I\left(0.35\;Tm^2\right)\nonumber\]
Magnetic Dipole Moment - HyperPhysics
WEBMagnetic Dipole Moment. From the expression for the torque on a current loop, the characteristics of the current loop are summarized in its magnetic moment. . The magnetic moment can be considered to be a vector quantity with direction perpendicular to the current loop in the right-hand-rule direction. The torque is given by.
Magnetic moment | physics | Britannica
WEBIn physics, magnetic moment relates the strength of a magnetic field to the torque experienced by a magnetic object. Because of their intrinsic spin, electrons have a magnetic moment given by −9.28 × 10 −24 joule per tesla.
17.2: The SI Definition of Magnetic Moment - Physics LibreTexts
WEBThe SI unit for magnetic moment is clearly \(\text{N m T}^{-1}\). If an electric current \(I\) flows in a plane coil of area \(\textbf{A}\) (recall that area is a vector quantity – hence the boldface), the torque it will experience in a magnetic field is given by \[\boldsymbol{\tau} = I \textbf{A} \times \textbf{B}. \label{2}\]
Magnetic Moment | Brilliant Math & Science Wiki
WEBThe propensity of a current distribution to experience torque in a magnetic field (and also create its own magnetic field) is characterized by its magnetic moment. In electrostatics, electric charge can exist as single ( monopole ) charges.
7.4: Magnetic Moment - Physics LibreTexts
WEBThe magnetic moment of a magnet is equal to the maximum torque it experiences when in unit magnetic field. As already noted this maximum torque is experienced when the magnet is at right angles to the magnetic field.
WEBA moving charge or current creates a magnetic field in the surrounding space (in addition to E). The magnetic field exerts a force F. on any other moving charge or current present in that field. The magnetic field is a vector field each point in space.
Magnetic moment - Simple English Wikipedia, the free …
WEBThe magnetic moment of a magnet is a quantity that determines the force that the magnet can exert on electric currents and the torque that a magnetic field will exert on it. A loop of electric current, a bar magnet, an electron, a molecule, and a planet all have magnetic moments.
