A simple closed form expression, henceforth referred to as the near-field expression, for the magnetic field of a solenoid is developed. The expression asymptotically approaches the exact values at radial distances large with respect to the diameter of the circular cross section of the solenoid. ...
Solenoid Magnetic FieldElliptic IntegralsThis paper presents the axial and radial magnetic fields strength equations at any point inside or outside a finite solenoid with infinitely thin walls. Solution of the equation has been obtained in terms of tabulated complete elliptic integrals. For the axial ...

The high-speed response solenoid valve (HSV) plays a key role in determining an electro-hydraulic automatic system's overall performance. As an approach to improving the HSV, this paper presents an optimal design method on the HSV's magnetic field by making a full consideration of the effects...

solenoid (ˈsəʊlɪˌnɔɪd) n 1.(Electronics) a coil of wire, usually cylindrical, in which a magnetic field is set up by passing a current through it 2.(Electronics) a coil of wire, partially surrounding an iron core, that is made to move inside the coil by the magn...
To Demonstrate the Magnetic Field around A Wire / Loop / Coil / Solenoid 1.Create a level surface perpendicular to the wire. 2.Using a power supply, send a current (~2A) through the wire. 3.Place a plotting compass near the wire and mark both ends of the needle on the surface. 4....
Suppose we take a solenoid: I was wondering what the magnetic field pattern would look like if the current-carrying wire in the depicted solenoid was replaced by a solenoid would look like. In other words, what would the magnetic field pattern look like if we made a solenoid out of a cur...
Solenoidal Field a vector field that has no source. In other words, the divergence of a vector a of a solenoidal field is equal to zero: div a = 0. An example of a solenoidal field is a magnetic field: div B = 0, where B is the magnetic induction vector. A solenoidal field can ...
