Magnetic dipole - Wikipedia
In electromagnetism, a magnetic dipole is the limit of either a closed loop of electric current or a pair of poles as the size of the source is reduced to zero while keeping the magnetic moment …
Dipole - Wikipedia
Dipole. The magnetic field of a sphere with a north magnetic pole at the top and a south magnetic pole at the bottom. By comparison, Earth has a south magnetic pole near its north geographic …
Magnetic dipole | Definition, Formula, Units, Examples, & Facts ...
magnetic dipole, generally a tiny magnet of microscopic to subatomic dimensions, equivalent to a flow of electric charge around a loop. Electrons circulating around atomic nuclei, electrons …
Dipole Magnetic Field and Equations of Magnetic Field Lines. 1.1. Dipole Magnetic Field. Since ∇ ⋅ B = 0 we can define. B = ∇ × A (1.1) where A is called the vector potential. We use the bold …

Nov 26, 2018 · Magnetic Dipole Moment and Connection with Torque on a Coil. The magnetic dipole moment represents the magnitude of the field of the dipole, essentially its magnetic …
The field is equivalent to that from a tiny bar magnet (a magnetic dipole). We define the magnetic dipole moment to be a vector pointing out of the plane of the current loop and with a …
