what is solenoid ? explain ?

$\mathtt\blue{Answer}$

Solenoid is a type of electromagnet, the purpose of which is to generate a controlled magnetic field through a coil wound into a tightly packed helix.

The coil can be arranged to produce a uniform magnetic field in a volume of space when an electric current is passed through it.

The term solenoid was coined in 1823 by André-Marie Ampère to designate a helical coil.

$\mathit\green{Required \: attachment : }$

$\huge\mathfrak\red{Formulae \: - }$

$B=\mu_{0} \frac{N I}{l}$

B = solenoid magnetic flux density

$\mu_{0}$= magnetic constant

{N} = number of turns

I = current

${l} = length \: of \: the \: solenoid .$
