Solenoid Magnetic Field Calculation. At the center of a long solenoid. Active formula: click on the quantity you wish to calculate. Magnetic field = permeability x turn density x current. For a solenoid of length L = m with N = turns, the turn density is n=N/L = turns/m. If the current in the solenoid is I = amperes.The inductance, L, is defined in terms of the current, I, flowing through the system, and Wm, the magnetic energy density is proportional to B2. The magnetic field, B, exists within and outside of the wire. Within the wire, it increases linearly outwards from the centerline, and outside of the wire it falls off as 1/ r, where r is the radius.The induced electric field in the coil is constant in magnitude over the cylindrical surface, similar to how Ampere’s law problems with cylinders are solved. Since →E is tangent to the coil, ∮→E ⋅ d→l = ∮Edl = 2πrE. When combined with Equation 13.5.5, this gives. E = ϵ 2πr.Vector Differentiation - F=(x+3y)i+(y-2z)j+(x+pz)k is a solenoidal Find p

In the mathematics of vector calculus, a solenoidal vector field is also known as a divergence-free vector field, an incompressible vector field, or a transverse vector field.

The solenoidal structure appears to need histone H1 for its stabilization. Under certain conditions, isolated nucleosomes can also aggregate into a similar structure. The solenoidal structure can be correlated with the "thread" of diameter about 300 A observed by other workers in nuclei.

Function. The solenoid structure's most obvious function is to help package the DNA so that it is small enough to fit into the nucleus. This is a big task as the nucleus of a mammalian cell has a diameter of approximately 6 µm, whilst the DNA in one human cell would stretch to just over 2 metres long if it were unwound. [6]

In solenoidal magnets the hoop stress is tensile along the longitudinal direction of the conductor.
