Solenoid mathematics
WebSolenoids were first defined by L. Vietoris [a2] (for the sequence $ \langle 2, 2 ,\dots \rangle $) and by D. van Dantzig [a1] (for all constant sequences). Solenoids are also important in … WebMar 24, 2024 · A solenoidal vector field satisfies del ·B=0 (1) for every vector B, where del ·B is the divergence. If this condition is satisfied, there exists a vector A, known as the vector potential, such that B=del xA, (2) where del xA is the curl. This follows from the vector identity del ·B=del ·(del xA)=0. (3) If A is an irrotational field, then Axr (4) is solenoidal.

WebSolenoidal definition, of or relating to a solenoid. See more. WebMay 29, 2012 · A solenoid is a helical coil wound around a cylinder. When a current runs through the coil a magnetic field is created. The strength of the magnetic field is proportional to the number of turns. This Demonstration approximates the field using the Biot–Savart law by way of superposition point sources in the plane.
