Question

what is solinoid ???????​

Answer 1

A 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.

hope it helps✌

$\red\longrightarrow\:\bf\blue{B\:=\:\mu_o\:\dfrac{N~I}{l}~}$

Where,

• B = Solenoid magnetic flux density

• $\bf{\mu_o}$ = Magnetic constant

• N = Number of turns

• I = Current

• l = Length of the solenoid
