- The work done against the induced emf in building up the current from 0 to I is
W = {tex}\int d W=\int \mathfrak{E} I d t=\int L \frac{d I}{d t} I d t=\int_{0}^{I} L I d I=\frac{1}{2} L I^{2}{/tex}
The magnetic energy stored in the solenoid is
UB = W = {tex}\frac{1}{2} L I^{2}=\frac{1}{2} L\left(\frac{B}{\mu_{0} n}\right)^{2}{/tex} {tex}\left[\because B=\mu_{0} n I\right]{/tex}
= {tex}\frac{1}{2}\left(\mu_{0} n^{2} A l\right)\left(\frac{B}{\mu_{0} n}\right)^{2}{/tex} {tex}\left[\because L=\mu_{0} n^{2} A l\right]{/tex}
{tex}U_{B}=\frac{1}{2 \mu_{0}} B^{2} A l{/tex} - The magnetic energy stored per unit volume of the solenoid is
{tex}u_{B}=\frac{U_{B}}{V}=\frac{U_{B}}{A l}{/tex} [Here V is the volume that contains flux]
[Here V is volume that contains flux]
or {tex} u_{B}=\frac{B^{2}}{2 \mu_{0}}{/tex} ....(i)
We know that the electrostatic energy stored per unit volume in a parallel plate capacitor is
{tex}u_{E}=\frac{1}{2} \varepsilon_{0} E^{2}{/tex} .....(ii)
In both the cases energy is proportional to the square of the field strengths. Eqs. (i) and (ii) are general and valid for any region of space in which a magnetic field or/and an electric field exist.

Co-primes are 2 numbers which have only one as a common factor.
a = 2160
b = 847
By Euclid's lemma a=bq+r, 0≤r<b
2160 = 847 × 2 + 466
847 = 466 × 1 + 381
466 = 381 × 1 + 85
381 = 85 × 4 + 41
85 = 41 × 2 + 3
41 = 3 × 13 + 2
3 = 2 × 1 + 1
2 = 1 × 2 + 0
As 1 is the HCF of 847 and 2160.
∴ 847 and 2160 are co-primes as they have only 1 as their HCF.

Klinefelter syndrome is one of the genetic disorders in males. It occurs when a male baby is born with more than required or extra X chromosomes. Many males consist of one X and one Y chromosome and an extra chromosome can cost a male with physical traits which are inappropriate for males.

It is this scattered light that gives the surrounding sky its brightness and its color. As previously stated, Rayleigh scattering is inversely proportional to the fourth power of wavelength, so that shorter wavelength violet and blue light will scatter more than the longer wavelengths (yellow and especially red light).
