Question

how is magnetic field in a solenoid..? ​

Answer 1

Answer:

hy

Explanation:

$\huge\boxed{\fcolorbox{white}{pink}{answer}}$

A solenoid is a long coil of wire wrapped in many turns. When a current passes through it, it creates a nearly uniform magnetic field inside. ... The energy density of the magnetic field depends on the strength of the field, squared, and also upon the magnetic permeability of the material it fills.

Answer 2

Explanation:

$\huge\underbrace\pink{Answer}$

The magnetic field inside a solenoid is proportional to both the applied current and the number of turns per unit length. There is no dependence on the diameter of the solenoid, and the field strength doesn't depend on the position inside the solenoid, i.e., the field inside is constant.
